20.500.12556/RUL-165177 Dynamical exciton condensates in biased electron-hole bilayers Bilayer materials may support interlayer excitons comprised of electrons in one layer and holes in the other. In experiments, a nonzero exciton density is typically sustained by a bias chemical potential, implemented either by optical pumping or by electrical contacts connected to the two layers. We show that if charge can tunnel between the layers, the chemical potential bias means that an exciton condensate is in the dynamical regime of ac Josephson effect. It has physical consequences such as tunneling currents and the ability to tune a condensate from bright (emitting coherent photons) to dark by experimental controlling knobs. If the system is placed in an optical cavity, coupling with cavity photons favors different dynamical states depending on the bias, realizing superradiant phases. condensed matter physics fizika kondenzirane snovi true false true Angleški jezik Slovenski jezik Članek v reviji 2024-11-26 10:20:29 2024-11-26 10:20:30 2024-11-27 03:50:48 0000-00-00 00:00:00 2024 0 0 Str. 217002-1-217002-9 iss. 21 Vol. 133 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 0031-9007 10.1103/PhysRevLett.133.217002 216468995 PhysRevLett.133.217002.pdf PhysRevLett.133.217002.pdf 1 B92DCBF0FF6F1F4E447B02AB307C92FC ff062749369c3c4a60b24b6c780661280b42e1326f2a34f9ab35d35e1990ce1d fc77be24-abd7-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196179 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.133.217002 0 02d33bd8-abd8-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196180 Fakulteta za matematiko in fiziko 0 0 0
