Dissipative preparation of a Floquet topological insulator in an optical lattice via bath engineering
Alexander Schnell, Christof Weitenberg, André Eckardt
Floquet engineering is an important tool for realizing topologically nontrivial band structures for charge-neutral atoms in optical lattices. However, the preparation of a topologi…
Indication of critical scaling in time during the relaxation of an open quantum system
Ling-Na Wu, Jens Nettersheim, Julian Feß +6
Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields. Near continuous phase tr…
Floquet-heating-induced Bose condensation in a scar-like mode of an open driven optical-lattice system
Alexander Schnell, Ling-Na Wu, Artur Widera +1
Periodically driven quantum systems suffer from heating via resonant excitation. While such Floquet heating guides a generic isolated system towards the infinite-temperature state,…
Charge density wave and charge pump of interacting fermions in circularly shaken hexagonal optical lattices
Tao Qin, Alexander Schnell, Klaus Sengstock +3
We analyze strong correlation effects and topological properties of interacting fermions with a Falicov-Kimball type interaction in circularly shaken hexagonal optical lattices, wh…
On the number of Bose-selected modes in driven-dissipative ideal Bose gases
Alexander Schnell, Roland Ketzmerick, André Eckardt
In an ideal Bose gas that is driven into a steady state far from thermal equilibrium, a generalized form of Bose condensation can occur. Namely, the single-particle states unambigu…
High-temperature nonequilibrium Bose condensation induced by a hot needle
Alexander Schnell, Daniel Vorberg, Roland Ketzmerick +1
We investigate theoretically a one-dimensional ideal Bose gas that is driven into a steady state far from equilibrium via the coupling to two heat baths: a global bath of temperatu…
