Thermodynamics of quantum-jump trajectories of open quantum systems subject to stochastic resetting
Gabriele Perfetto, Federico Carollo, Igor Lesanovsky
We consider Markovian open quantum systems subject to stochastic resetting, which means that the dissipative time evolution is reset at randomly distributed times to the initial st…
Fast spin squeezing by distance-selective long-range interactions with Rydberg molecule dressing
Huaizhi Wu, Xin-Yu Lin, Zong-Xing Ding +3
We propose a Rydberg molecule dressing scheme to create strong and long-ranged interactions at selective distances. This is achieved through laser coupling ground-state atoms off-r…
Quantum fluctuations and correlations in open quantum Dicke models
Mario Boneberg, Igor Lesanovsky, Federico Carollo
In the vicinity of ground-state phase transitions quantum correlations can display non-analytic behavior and critical scaling. This signature of emergent collective effects has bee…
Exact solution of a boundary time-crystal phase transition: time-translation symmetry breaking and non-Markovian dynamics of correlations
Federico Carollo, Igor Lesanovsky
The breaking of the continuous time-translation symmetry manifests, in Markovian open quantum systems, through the emergence of non-stationary dynamical phases. Systems that displa…
Phase diagram of quantum generalized Potts-Hopfield neural networks
Eliana Fiorelli, Igor Lesanovsky, Markus Müller
We introduce and analyze an open quantum generalization of the q-state Potts-Hopfield neural network, which is an associative memory model based on multi-level classical spins. The…
Designing non-equilibrium states of quantum matter through stochastic resetting
Gabriele Perfetto, Federico Carollo, Matteo Magoni +1
We consider closed quantum many-body systems subject to stochastic resetting. This means that their unitary time evolution is interrupted by resets at randomly selected times. When…
