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…
Canonically consistent quantum master equation
Tobias Becker, Alexander Schnell, Juzar Thingna
We put forth a new class of quantum master equations that correctly reproduce the asymptotic state of an open quantum system beyond the infinitesimally weak system-bath coupling li…
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,…
High-frequency expansions for time-periodic Lindblad generators
Alexander Schnell, Sergey Denisov, André Eckardt
Floquet engineering of isolated systems is often based on the concept of the effective time-independent Floquet Hamiltonian, which describes the stroboscopic evolution of a periodi…
Describing many-body localized systems in thermal environments
Ling-Na Wu, Alexander Schnell, Giuseppe De Tomasi +2
In this work we formulate an efficient method for the description of many-body localized systems in weak contact with thermal environments at temperature . For this purpose we e…
