Topology, localization, and spontaneous symmetry breaking in nonequilibrium many-body systems
Exotic many-body phenomena are usually associated with the ground state of a time-independent Hamiltonian. It is natural to ask whether these physics can survive in a dynamic setting. Under a generic drive, the steady equilibrium state is most likely an infinite-temperature featureless thermal …

Exploring Interacting Bose Gases in and out of Equilibrium
… an optical box trap, a novel testbed for quantum many-body phenomena. Our work focuses on weakly interacting non-equilibrium systems, moderately interacting systems that are still in equilibrium, and the unitary Bose gas which is both strongly interacting and eludes equilibrium. We begin with …

Luminescent Harnessing of 2D Transition Metal Dichalcogenide Excitons
… tightly bound excitons that exhibit intriguing many-body phenomena. 2D excitons may be transferred to other emissive materials in a heterostructure system. This has applications in e.g., photon harvesting with luminescent solar concentrators (LSCs). Newly prepared monolayers are however …
