We numerically study out-of-equilibrium dynamics in a family of Heisenberg models with $\frac{1}{r^6}$ power-law interactions and positional disorder. Using the semi-classical discrete truncated Wigner approximation (dTWA) method, we investigate the …

Path integrals with complex actions are encountered for many physical systems ranging from spin- or mass-imbalanced atomic gases and graphene to quantum chromo-dynamics at finite density to the non-equilibrium evolution of quantum systems. Many …

We derive inseparability criteria for the phase space representation of quantum states in terms of variants of Wehrl's entropy. In contrast to entropic criteria involving differential entropies of marginal phase space distributions, our criteria are …

We study excitation transport in a two-dimensional system of randomly assembled spins with power-law hopping in two dimensions. This model can be realized in cold atom quantum simulators with Rydberg atoms. In these experiments, due to the Rydberg …

A prerequisite for the comprehensive understanding of many-body quantum systems is a characterization in terms of their entanglement structure. The experimental detection of entanglement in spatially extended many-body systems describable by quantum …

We study out-of-equilibrium dynamics in the quantum Ising model with power-law interactions and positional disorder. For arbitrary dimension d and interaction range α≥d we analytically find a stretched exponential decay with stretch power β=d/α for …

We develop a variational approach to simulating the dynamics of open quantum many-body systems using deep autoregressive neural networks. The parameters of a compressed representation of a mixed quantum state are adapted dynamically according to the …

We experimentally investigate the nonlinear transmission spectrum of coherent light fields propagating through a Rydberg-EIT medium with strong atomic interactions. In contrast to previous investigations, which have largely focused on resonant …

We study experimentally accessible lower bounds on entanglement measures based on entropic uncertainty relations. Experimentally quantifying entanglement is highly desired for applications of quantum simulation experiments to fundamental questions, …

Entanglement is not only the resource that fuels many quantum technologies but also plays a key role for some of the most profound open questions of fundamental physics. Experiments controlling quantum systems at the single quantum level may shed …
