Limits of topological protection under local periodic driving
Zlata Cherpakova, Christina Jörg, Christoph Dauer +5
The bulk-edge correspondence guarantees that the interface between two topologically distinct insulators supports at least one topological edge state that is robust against static…
Adiabatic flux insertion and growing of Laughlin states of cavity Rydberg polaritons
Peter A. Ivanov, Fabian Letscher, Jonathan Simon +1
Recently, the creation of photonic Landau levels in a twisted cavity has been demonstrated in Nature \textbf{534}, 671 (2016). Here we propose a scheme to adiabatically transfer fl…
Mobile bound states of Rydberg excitations in a lattice
Fabian Letscher, David Petrosyan
Spin lattice models play central role in the studies of quantum magnetism and non-equilibrium dynamics of spin excitations -- magnons. We show that a spin lattice with strong neare…
Many-body dynamics of holes in a driven, dissipative spin chain of Rydberg superatoms
Fabian Letscher, David Petrosyan, Michael Fleischhauer
Strong dipole-dipole interactions between atoms in high-lying Rydberg states can suppress multiple Rydberg excitations within a micron-sized trapping volume and yield sizable Rydbe…
Dynamic defects in photonic Floquet topological insulators
Christina Jörg, Fabian Letscher, Michael Fleischhauer +1
Edge modes in topological insulators are known to be robust against defects. We investigate if this also holds true when the defect is not static, but varies in time. We study the…
Anomalous excitation facilitation in inhomogeneously broadened Rydberg gases
Fabian Letscher, Oliver Thomas, Thomas Niederprüm +2
When atomic gases are laser driven to Rydberg states in an off resonant way, a single Rydberg atom may enhance the excitation rate of surrounding atoms. This leads to a facilitated…
