Quantum information scrambling in strongly disordered Rydberg spin systems
Maximilian Müllenbach, Sebastian Geier, Adrian Braemer +5
Despite the fact that power-law interactions occur in a plethora of physical systems, their many-body dynamics is far less understood than that of nearest-neighbor interacting syst…
Observation of hysteresis in an isolated quantum system of disordered Heisenberg spins
Moritz Hornung, Eduard J. Braun, Sebastian Geier +3
We find energy-dependent hysteresis in an isolated Heisenberg quantum spin system, similar to thermomagnetic hysteresis in canonical spin glasses in contact with a thermal reservoi…
Time-reversal in a dipolar quantum many-body spin system
Sebastian Geier, Adrian Braemer, Eduard Braun +5
Time reversal in a macroscopic system is contradicting daily experience. It is practically impossible to restore a shattered cup to its original state by just time reversing the mi…
A stationary Rydberg polariton
Annika Tebben, Clément Hainaut, Andre Salzinger +4
We propose a novel scheme for coupling a Rydberg state to a stationary light polariton, based on a dual-V level scheme. We investigate the properties of the resulting stationary Ry…
Glassy dynamics in a disordered Heisenberg quantum spin system
A. Signoles, T. Franz, R. Ferracini Alves +4
Understanding the dynamics of strongly interacting disordered quantum systems is one of the most challenging problems in modern science, due to features such as the breakdown of th…
