Extensive mixed-state entanglement in kinetically constrained superradiance
Lucas Winter, Jan Kumlin, Thomas Pohl +1
Dicke superradiance by an ensemble of quantum emitters produces a collective burst of radiation, but no entanglement in the mixed state of the emitters. We show that adding a local…
Self-Induced Superradiant Masing
Wenzel Kersten, Nikolaus de Zordo, Oliver Diekmann +9
In cavity quantum electrodynamics (cQED) and particularly superradiance, emitters are typically assumed to be independent, interacting only through light shared via a common mode.…
Superradiance of Strongly Interacting Dipolar Excitons in Moiré Quantum Materials
Jan Kumlin, Ajit Srivastava, Thomas Pohl
Moiré lattices created in two-dimensional heterostructures exhibit rich many-body physics of interacting electrons and excitons and, at the same time, suggest promising optoelectr…
Signatures of collective photon emission and ferroelectric ordering of excitons near their Mott insulating state in a WSe/WS heterobilayer
Luka Matej Devenica, Zach Hadjri, Jan Kumlin +11
Spontaneous symmetry breaking, arising from the competition of interactions and quantum fluctuations, is fundamental to understanding ordered electronic phases. Although electrical…
