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…
Realization of a doped quantum antiferromagnet with dipolar tunnelings in a Rydberg tweezer array
Mu Qiao, Gabriel Emperauger, Cheng Chen +13
Doping an antiferromagnetic Mott insulator is central to our understanding of a variety of phenomena in strongly-correlated electrons, including high-temperature superconductors. T…
Supersolidity in Rydberg tweezer arrays
Lukas Homeier, Simon Hollerith, Sebastian Geier +3
Rydberg tweezer arrays provide a versatile platform to explore quantum magnets with dipolar XY or van-der-Waals Ising ZZ interactions. Here, we propose a scheme combining dipolar a…
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…
