Applications are invited for a postdoctoral research position in condensed matter theory at the University of Wisconsin – Madison. The appointment will be for two years, with possibility of renewal for a third year contingent on funding and progress made. The start date is expected to be Fall 2023 but is negotiable. The successful candidate will work under the joint supervision of Prof. Alex Levchenko and Prof. Ilya Esterlis. Topics of current interest include (but are not limited to): (1) superconductivity in both conventional and unconventional systems, including the interplay between anomalous metallic behavior and superconductivity; (2) properties of the two-dimensional electron gas at intermediate and strong coupling, including Wigner crystal and related phases; (3) optical probes
