Giant Hyperfine Interaction between a Dark Exciton Condensate and Nuclei
Amit Jash, Michael Stern, Subhradeep Misra +2
We study the interaction of a dark exciton Bose-Einstein condensate with the nuclei in GaAs/AlGaAs coupled quantum wells and find clear evidence for nuclear polarization buildup th…
Field-induced hybridization of moiré excitons in MoSe/WS heterobilayers
Borislav Polovnikov, Johannes Scherzer, Subhradeep Misra +10
We study experimentally and theoretically the hybridization among intralayer and interlayer moiré excitons in a MoSe/WS heterostructure with antiparallel alignment. Using a…
Coulomb-correlated states of moiré excitons and charges in a semiconductor moiré lattice
Borislav Polovnikov, Johannes Scherzer, Subhradeep Misra +10
Semiconductor moiré heterostructures exhibit rich correlation-induced many-body phenomena with signatures of emergent magnetism, Mott insulating states or generalized Wigner crysta…
The Role of Spin-Flip Collisions in a Dark Exciton Condensate
Subhradeep Misra, Michael Stern, Vladimir Umansky +1
We show that a Bose-Einstein condensate consisting of dark excitons forms in GaAs coupled quantum wells at low temperatures. We find that the condensate extends over hundreds of mi…
Experimental Study of the Exciton Gas Liquid Transition in Coupled Quantum Wells
Subhradeep Misra, Michael Stern, Arjun Joshua +2
We study the exciton gas-liquid transition in GaAs/AlGaAs coupled quantum wells. Below a critical temperature, Tc=4.8K, and above a threshold laser power density the system undergo…
