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…
Optimizing Design Choices for Neural Quantum States
Moritz Reh, Markus Schmitt, Martin Gärttner
Neural quantum states are a new family of variational ansätze for quantum-many body wave functions with advantageous properties in the notoriously challenging case of two spatial d…
Pair localization in dipolar systems with tunable positional disorder
Adrian Braemer, Titus Franz, Matthias Weidemüller +1
Strongly interacting quantum systems subject to quenched disorder exhibit intriguing phenomena such as glassiness and many-body localization. Theoretical studies have mainly focuse…
Exploring adiabatic quantum dynamics of the Dicke model in a trapped ion quantum simulator
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a quantum simulator of the Dicke Hamiltonian.…
Collective excitation of Rydberg-atom ensembles beyond the enhancement
Martin Gärttner, Shannon Whitlock, David W. Schönleber +1
In an ensemble of laser-driven atoms involving strongly interacting Rydberg states, the excitation probability is usually strongly suppressed. In contrast, here we identify a regim…
