Exploiting emergent symmetries in disorder-averaged quantum dynamics
Mirco Erpelding, Adrian Braemer, Martin Gärttner
Symmetries are a key tool in understanding quantum systems, and, among many other things, can be exploited to increase the efficiency of numerical simulations of quantum dynamics.…
Quantum information scrambling in strongly disordered Rydberg spin systems
Maximilian Müllenbach, Sebastian Geier, Adrian Braemer +6
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…
Cluster truncated Wigner approximation for bond-disordered Heisenberg spin models
Adrian Braemer, Javad Vahedi, Martin Gärttner
We present a comprehensive numerical investigation of the cluster Truncated Wigner Approximation (cTWA) applied to quench dynamics in bond-disordered Heisenberg spin chains with po…
Observation of anisotropy-independent magnetization dynamics in spatially disordered Heisenberg spin systems
Titus Franz, Sebastian Geier, Clément Hainaut +7
An important step towards a comprehensive understanding of far-from-equilibrium dynamics of quantum many-body systems is the identification of unifying features that are independen…
