UConn Physics alumnus Dr. Michael Wininger (BS, 2003) was recently featured in the professional journal O&P Almanac (Orthotics and Prosthetics). The article describes how his eclectic background, beginning with degrees from UConn, has enabled him to lead innovations in several areas of health research. Mike is currently an Assistant Clinical Professor in the Biostatistics Department at the Yale School of Public Health while also holding a co-appointment with the Department of Veterans Affairs Cooperative Studies Program. Michael says that former Professor Ed Pollack was particularly instrumental in mentoring towards a successful career, and in gratitude has been a frequent contributor to the Edward Pollack Endowment Fund, which supports our annual Pollack Lecture in Atomic Physics. Some of the old-timers around the department remember Mike for his always energetic presence around the department and help with our bicycles.
Dear Friends of UConn Physics,
Due to the current health situation and concerns surrounding the Corona virus, we are canceling the Katzenstein Lecture and Banquet scheduled for Friday, March 13, 2020.
It was an agonizing decision to cancel, but our first priority is the health of all who would have been attending, our special guest Professor Strickland, and the UConn community. I extend an extra apology for those of you who have planned to travel a considerable distance and will need to change plans. For those who have signed up for the banquet, we are working to arrange refunds.
If all goes well, the current health crisis will be behind us soon and we will see if we can reschedule Professor Strickland for another, safer time.
Again, my apologies and best wishes,
Barrett O. Wells
Professor and Head, Department of Physics
The University of Connecticut, Department of Physics, is proud to announce that on March 13, 2020, Professor Donna Strickland of the Department of Physics and Astronomy at the University of Waterloo will be presenting the 2020 Distinguished Katzenstein Lecture. Prof. Strickland is one of the recipients of the 2018 Nobel Prize in Physics for developing chirped pulse amplification with Gérard Mourou, her PhD supervisor. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York State. Together they paved the way toward the most intense laser pulses ever created. The research has several applications today in industry and medicine — including the cutting of a patient’s cornea in laser eye surgery, and the machining of small glass parts for use in cell phones.
Prof. Strickland earned a Bachelor in Engineering from McMaster University and a PhD in optics from the University of Rochester. She was a research associate at the National Research Council Canada, a physicist at Lawrence Livermore National Laboratory and a member of technical staff at Princeton University. In 1997, she joined the University of Waterloo, where her ultrafast laser group develops high-intensity laser systems for nonlinear optics investigations. She is a recipient of a Sloan Research Fellowship, the Ontario Premier’s Research Excellence Award and a Cottrell Scholar Award. She received the Rochester Distinguished Scholar Award and the Eastman Medal from the University of Rochester.
Prof. Strickland served as the president of the Optical Society (OSA) in 2013 and is a fellow of OSA, the Royal Society of Canada, and SPIE (International Society for Optics and Photonics). She is an honorary fellow of the Canadian Academy of Engineering as well as the Institute of Physics. She received the Golden Plate Award from the Academy of Achievement, is in the International Women’s Forum Hall of Fame, and holds numerous honorary doctorates.

Reception: at 3pm in the Gant Light Court
Could traveling into the past be part of our future? Quite possibly, says Ron Mallett, a UConn emeritus professor of physics who has studied the concept of time travel for decades. Earlier this month, he spoke with NBC Connecticut reporter Kevin Nathan about his life and work as a theoretical physicist, and discussed how time travel may be possible someday.
The UConn Physics Department is delighted to announce that our 2019 Distinguished Katzenstein Lecturer will be
Professor Dame Jocelyn Bell Burnell
Friday, November 8th, 2019
04:00 PM – 05:00 PM
Storrs Campus, Student Union Theater
Professor Dame Jocelyn Bell Burnell (pictured at left) is world-famous for her discovery of pulsars in 1967. Pulsars are a special type of neutron star, the rotating dense remnant of a massive star. Pulsars have highly magnetic surfaces and emit a beam of electromagnetic radiation along their poles. This beam of light moves into and out of our line-of-sight at quick, constant intervals, appearing as a regular “pulse” of light.
At the time of this discovery, Bell Burnell was a graduate student at the University of Cambridge and worked with her supervisor, Anthony Hewish, to construct the Interplanetary Scintillation Array to study another class of objects called quasars. In the course of her daily detailed analysis, she noticed a strange “pulsing” signal in her data. Jokingly dubbed “Little Green Man 1” (LGM-1), further data-taking and analysis revealed this signal to be rapidly spinning neutron star, eventually dubbed a “pulsar.”
Bell Burnell’s discovery is considered one of the most important achievements of the 20th century and was recognized by a Nobel Prize in Physics in 1974, awarded to her supervisor Anthony Hewish as well as to astronomer Martin Ryle. While many condemned the omission of Bell Burnell for the award, she rose above, graciously stating, “I believe it would demean Nobel Prizes if they were awarded to research students, except in very exceptional cases, and I do not believe this is one of them. Finally, I am not myself upset about it – after all, I am in good company, am I not!”
Professor Dame Jocelyn Bell Burnell has a highly distinguished career. Some notable highlights include serving as head of the Royal Astronomical Society and as the first female president of both the Institute of Physics and The Royal Society of Edinburgh. She was appointed Dame Commander of the Order of the British Empire for services to astronomy in 2007. Her story has been featured in a number of works, including the BBC Four’s Beautiful Minds and BBC Two’s Horizon. Bell Burnell is currently the chancellor of the University of Dundee in Scotland and a visiting professor of astrophysics at the University of Oxford.
In 2018 Bell Burnell was awarded a Special Breakthrough Prize in Fundamental Physics. Only four such prizes have been awarded, one to Stephen Hawking, one to the CERN scientists who discovered the Higgs Boson, and one to the LIGO team for their detection of gravitational waves. This award recognizes her discovery of pulsars and “a lifetime of inspiring scientific leadership.” In addition to her research accolades, her teaching, leadership, and work to lift up women and minorities in science is without parallel.
New building, new teaching approach, new people – there is a lot of change and excitement in the air for the Physics Department in 2019. The most obvious change is that physics has moved into a newly renovated building. What most alumni will remember as the Math Building has been taken down to its frame and rebuilt as the new physics building, formally Gant South. The new building features large windows with lots of light, revamped teaching labs, and a theory suite at the east end of each hallway. There are also plenty of meeting rooms and nooks, complete with writing spaces, to foster spontaneous discussions. We moved into the offices and teaching spaces at the start of fall semester, whereas the research lab relocations are ongoing as I write.
Along with the new building comes new teaching laboratories. The most striking of these are our studio-labs, located in the Gant Plaza building in the center of the Gant Complex. These studio labs have allowed us to redesign how we teach our introductory physics with calculus courses. Instead of three one-hour lectures per week and a three hour lab, there are now three two-hour meetings per week with mixed activities. The rooms are arranged with groups sitting around tables, and class time is spent on group efforts to explore concepts, solve problems, and conduct laboratory measurements. We have been developing this program using the Phys 1601 and 1602 courses for physics majors. This fall we rolled out the first of four other courses to be taught in this method with Phys 1501, to be followed in successive semesters by Phys 1502, Phys 1401, and Phys 1402.
If your travels bring you to the Storrs area, please stop by our new building. I will give anyone interested a tour myself if my schedule allows.
We also have several new faces around the department this fall. We have hired two new assistant professors in astrophysics, Chiara Mingarelli and Daniel Angles-Alcazar. Both have been hired in a bridge program with the Flatiron Institute of the Simons Foundation. Simons is the leading philanthropic foundation focused on science, and the four centers hosted at the Flatiron are world leaders in computational methods. We also have two new full-time teaching faculty, Niraj Ghimire and Sarah Trallero. Niraj was our own Ph.D. student who had previously worked on our Studio Physics development team. Sarah has been working with our teaching lab support team, with previous experience at Kansas State teaching studio-style physics courses. We have several new members of our teaching lab support team, with three new technicians. Zach Transport and James Jaconetta began working with us last January, and Hannah Morrill joined us over the summer. And finally, while I am not a new face, I took over as department head about a year ago and this is my first go-round writing a welcome to our newsletter. I would like to personally thank Professor Nora Berrah, our past department head, for putting our department on a firm footing that has made my job much easier.
May 27-June 5 UConn Physics Department hosted an international summer school Strong interactions beyond simple factorization: collectivity at high energy from initial to final state. The school was supported by an NSF grant to Prof. Kovner and was devoted to modern approaches to the physics of high energy hadronic and heavy ion collisions.
On April 11th and 12 of 2019 Prof. Paul Corkum of the Joint Attosecond Laboratory (University of Ottawa and the National Research Council of Canada) visited the department. Prof. Corkum’s main area of research is on the interaction of ultrashort laser pulses with matter broadly defined. His most notable contribution is perhaps the discovery of the so-called three-step model, which has become the basis of the emerging field of attosecond science. Attoseconds, equal to 1 billionth of 1 billionth of a second (10-18 s) is the shortest time scale ever measured or controlled by humans and is at the forefront of modern optics.
Prof. Corkum is a member of the US National Academy of Sciences, the Russian Academy of Sciences, the Austrian Academy of Sciences, the Royal Canadian Academy of Sciences and the Royal Society of London. He has received many accolades throughout his career, including the Thomson Reuters Citation Laureate which is awarded to researchers who are “of Nobel class” and likely to earn the Nobel someday and the Order of Canada.
On April 12, Prof. Corkum presented the annual Edward Pollack Distinguished Lecture, entitled “Attosecond Pulses Generated in Gases and Solids”. This lecture is supported by an endowment established by the family of the late Professor Edward Pollack in 2005. Ed’s family, friends and colleagues made contributions in his memory. This special colloquium provides a presentation in Ed’s honor in the field of atomic, molecular and optical physics, his area of research expertise. This year Mrs. Rita Pollack and their three children: Cindy [U.S. Government civil servant], Lois [now a professor of applied physics at Cornell], and Howard [professor of modern languages (German) at dePauw University in Indiana] were all in attendance.
Below, dinner with the Pollack family members, UConn faculty, and guests.
The 2018 Reynolds lecture speaker was Prof Andrew Millis, a Professor of Physics at Columbia University and a co-Director of Center for Computational Quantum Physics at the Flatiron Institute. Dr. Millis’s research focus is theoretical condensed matter physics. He is the leading authority in theory of correlated materials, application of new theoretical ideas to actual experiments on novel materials including high temperature superconductors. His theory of ‘colossal’ magnetoresistance seen in manganites has been the key theoretical advance that enabled a complete understanding of these materials. Andrew has also been working on quasi one-dimensional conductors and heavy fermion compounds. The lecture, entitled “Meeting Dirac’s challenge: from quantum entanglement to materials theory” presented a broad-stroke account of developments in humankind’s capability of explaining and predicting materials properties through advanced computational approaches.
Dirac wrote 90 years ago: “The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.’’ Professor Millis described the development of the new computational tools to meet the challenge laid out by Dirac in our quest for effective predictive tools for quantum materials. Center for Computational Quantum Physics, The Flatiron Institute is superbly positioned to address this challenge. The lecture was held on March 15 2019 and was well attended with a large number of undergraduate and graduate students present.

About one mile from the Gant plaza, Goodwin Elementary School teaches some really bright kids. On January 15, 2019, science teacher Nancy Titchen and Goodwin teachers brought the entire 3rd grade class on a field trip to the Physics Learning Labs mock-up studio for some science fun. Students enjoyed a liquid nitrogen show, witnessed quantum effects in superconducting magnetic levitation, experienced mechanics concepts such as angular momentum, and learned about vibrations and the phenomenon mechanical of resonance. The expert hands of a star team of PhD students (Erin Curry and Donal Sheets) and new laboratory technicians (James Jaconetta and Zac Transport) ensured students had a great time and learned some interesting science. Big thanks to the staff and the Goodwin School!
The Katzenstein Distinguished Lectures series continued in the 2018 academic year with its twenty second Nobel Laureate lecturer, with an October 26, 2018 lecture by Professor Rainer Weiss of the Massachusetts Institute of Technology.
The title of Professor Weiss’ talk was “Exploration of the Universe with Gravitational Waves”, with abstract:
The observations of gravitational waves from the merger of binary black holes and from a binary neutron star coalescence followed by a set of astronomical measurements is an example of investigating the universe by “multi-messenger” astronomy. Gravitational waves will allow us to observe phenomena we already know in new ways as well as to test General Relativity in the limit of strong gravitational interactions – the dynamics of massive bodies traveling at relativistic speeds in a highly curved space-time. Since the gravitational waves are due to accelerating masses while electromagnetic waves are caused by accelerating charges, it is reasonable to expect new classes of sources to be detected by gravitational waves as well. The lecture will start with some basic concepts of gravitational waves, briefly describe the instruments and the methods for data analysis that enable the measurement of gravitational wave strains of one part in 10 to the 21, and then present the results of recent runs. The lecture will end with a vision for the future of gravitational wave astrophysics and astronomy.
In 2017 Professor Weiss shared the Nobel Prize in Physics with Professor Kip Thorne and Professor Barry Barish for their epochal discovery of gravitational waves, waves that had been predicted by Albert Einstein using his General Theory of Relativity no less than a hundred years before.
Professor Rainer Weiss received his BS degree from MIT in 1955 and his PhD from MIT in 1962. He was on the faculty of Tufts University from 1960 to 1962, and did post-doctoral research at Princeton from 1962 to 1964. He joined the MIT faculty in 1964 and remained a regular faculty member there until he became emeritus in 2001. Along with Kip Thorne, the late Ronald Drever and Barry Barish he spearheaded the development of LIGO, the Laser Interferometer Gravitational-Wave Observatory, a set of two interferometers, one located in Louisiana and the other in Washington State. The interferometers would jointly look for gravitational wave signals seen in coincidence, and in September 2015 made the very first detection of gravity waves. At Louisiana State University he has served as an Adjunct Professor of Physics since 2001. As well as research in gravity waves Professor Weiss’ other primary interests are in atomic clocks and cosmic microwave background measurements.
Dr. Weiss had previously visited the University of Connecticut in Fall 2015 as part of a lecture series that fall given at the University of Connecticut in commemoration of the hundredth year of Einstein’s development of his Theory of General Relativity. At that time Dr. Weiss described the ongoing search at LIGO for gravity waves produced by the merger of two black holes. And the initial announcement of a discovery was made in February 2016, shortly after Dr. Weiss’s visit to the University of Connecticut. It is also of interest to note that Dr. Shep Doeleman of Harvard University was another of the speakers at the Fall 2015 University of Connecticut Einstein commemoration. He talked about the ongoing effort to actually detect the event horizons associated with black holes using the Event Horizon Telescope, black holes being yet another prediction of Einstein’s Theory that was also one hundred years old. And in 2019 Dr. Doeleman announced the very the first direct detection of a black hole event horizon. Thus, with the first detection of gravity waves produced by black hole mergers and then the detection of an event horizon itself, the theory of black holes is put on a very secure observational foundation.
