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…
