Extreme Tuning of Quantum Materials
I will describe recent research directions in my lab studying quantum materials with important properties. One set of work studies unusual and strange phase transitions, particularly a case where the change in symmetry with temperature is opposite of that expected. Another involves developing methods to study the atomic structure and electromagnetic properties of materials in the form of nanopillars, where they can be subjected to strain fields orders of magnitude higher than possible in normal sized materials. The discovery of superelasticity in nanopillars came from a UConn colleague studying the strength of materials. The technique appears to open a path towards extreme tuning of quantum properties if proper measurement techniques can be developed. Our group is working to enable nanodiffraction of the atomic structure under extreme strain.
In addition, I will make some general remarks about the department in my role as Department Head.Contact Information: Prof. V. Kharchenko

Resurgence in QED: Probing the Schwinger effect in inhomogeneous fields
The structure of the QED vacuum is a subject of great interest, especially as experiments begin to more directly probe the non-linear regime of the theory. One of the most striking features of the vacuum is its polarization in the presence of an electric field — a non-perturbative phenomenon that leads to pair production. Detailed information about this non-perturbative structure is contained in the divergence of perturbation theory, which is more generally described by the theory of resurgence. We study the one-loop QED effective action for an exactly solvable, inhomogeneous background field configuration and use Borel summation to illustrate the connection between perturbative and non-perturbative regimes. Using only 15 terms in the weak magnetic field perturbative expansion, we extrapolate to both strong magnetic field and electric field configurations and obtain a pair-production rate that agrees with the exact effective action to remarkable precision.Contact Information: Prof. L.
