The Geophysics research group (Prof. Vernon Cormier and students) operate a seismic wave station that continuously monitors vibrations in the earth’s crust, many of which arise from seismic events that happen far away. These waves travel through the deep earth, and eventually make their way to the surface where they are detected. The above figures show high frequency and low frequency filtered seismograms recorded at UConn’s seismic station for the vertical component of ground motion from the earthquakes in Puerto Rico on January 7, 2020. The 3 bursts of energy are P and S elastic waves, followed by a T wave, which propagates as an acoustic wave in the ocean. In the high frequency seismogram (first figure), the large red trace is the main shock and the black trace below it is an aftershock. In the low frequency filtered seismogram (second figure), the largest energy propagates as a surface wave trapped in Earth’s crust and upper most mantle, with energy exponentially decaying into the mantle. Amplitude scale for ground particle velocity is shown by a bar in the upper left corner.
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.

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 Today published an article highlighting the state of 10-year renovation of the Gant Science Complex. The Complex was first constructed between 1974 and 1978 and was home to the departments of mathematics and physics for several decades. The renovation to this 285,00 square-foot campus landmark is part of Next Generation Connecticut, the initiative to expand educational opportunities, research, and innovation in the science, technology, engineering, and math (STEM) disciplines at UConn.
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.
The Daily Campus published an article highlighting the research of Prof. Thomas Blum about Quantum Chromodynamics, a theory which describes the interactions between elementary particles. The development of this theory could help further understanding of the Standard Model of particle physics. The Standard Model is what physicists use to describe the fundamental building blocks of everything in the universe.
UConn Astrophysicist and observational astronomer Jonathan Trump was a recent guest on UConn 360, a podcast from the Storrs campus of the University of Connecticut. In this conversation, Jonathan tells about how attending a lecture as an undergraduate at Penn State captured his interest and changed the course of his professional career. Now Jonathan offers similar career-changing opportunities to UConn students, who just this year have applied for and obtained dedicated time for observations by the Hubble space telescope.
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.
