DOI: 10.1021/acs.nanolett.2c03796

Abstract: Propagation of light-emitting quasiparticles is of central importance across the fields of condensed matter physics and nanomaterials science. We experimentally demonstrate diffusion of excitons in the presence of a continuously tunable Fermi sea of free… read more here.

DOI: 10.1103/physreva.102.033322

Abstract: We present a variational calculation of the energy of an impurity immersed a double Fermi sea of non-interacting Fermions. We show that in the strong-coupling regime, the system undergoes a first order transition between polaronic… read more here.

DOI: 10.1103/physreva.102.051302

Abstract: We propose a protocol to examine many-polaron properties in a cold atom experiment. Initially, polaronic clouds are prepared around the opposite edges of a majority gas cloud. After time evolution, the collision of two clouds… read more here.

DOI: 10.1103/physrevlett.130.096301

Abstract: We show that the topology of the Fermi sea of a two-dimensional electron gas (2DEG) is reflected in the ballistic Landauer transport along a long and narrow Josephson π junction that proximitizes the 2DEG. The… read more here.
