Quantum trajectories of dissipative time-crystals
Albert Cabot, Leah Sophie Muhle, Federico Carollo +1
Recent experiments with dense laser-driven atomic gases [G. Ferioli et al., arXiv:2207.10361 (2022)] have realized a many-body system which in the thermodynamic limit yields a so-c…
Collective atom-cavity coupling and non-linear dynamics with atoms with multilevel ground states
Elmer Suarez, Federico Carollo, Igor Lesanovsky +3
We investigate experimentally and theoretically the collective coupling between atoms with multilevel ground state manifolds and an optical cavity mode. In our setup the cavity fie…
Using (1 + 1)D Quantum Cellular Automata for Exploring Collective Effects in Large Scale Quantum Neural Networks
Edward Gillman, Federico Carollo, Igor Lesanovsky
Central to the field of quantum machine learning is the design of quantum perceptrons and neural network architectures. A key question in this regard is the impact of quantum effec…
Many-body radiative decay in strongly interacting Rydberg ensembles
Chris Nill, Kay Brandner, Beatriz Olmos +2
When atoms are excited to high-lying Rydberg states they interact strongly with dipolar forces. The resulting state-dependent level shifts allow to study many-body systems displayi…
Metastable discrete time-crystal resonances in a dissipative central spin system
Albert Cabot, Federico Carollo, Igor Lesanovsky
We consider the non-equilibrium behavior of a central spin system where the central spin is periodically reset to its ground state. The quantum mechanical evolution under this effe…
Accelerating the approach of dissipative quantum spin systems towards stationarity through global spin rotations
Simon Kochsiek, Federico Carollo, Igor Lesanovsky
We consider open quantum systems whose dynamics is governed by a time-independent Markovian Lindblad Master equation. Such systems approach their stationary state on a timescale th…
Emergent quantum correlations and collective behavior in non-interacting quantum systems subject to stochastic resetting
Matteo Magoni, Federico Carollo, Gabriele Perfetto +1
We investigate the dynamics of a non-interacting spin system, undergoing coherent Rabi oscillations, in the presence of stochastic resetting. We show that resetting generally induc…
Asynchronism and nonequilibrium phase transitions in D quantum cellular automata
Edward Gillman, Federico Carollo, Igor Lesanovsky
Probabilistic cellular automata provide a simple framework for the exploration of classical nonequilibrium processes. Recently, quantum cellular automata have been proposed that re…
Inferring Markovian quantum master equations of few-body observables in interacting spin chains
Francesco Carnazza, Federico Carollo, Dominik Zietlow +3
Full information about a many-body quantum system is usually out-of-reach due to the exponential growth -- with the size of the system -- of the number of parameters needed to enco…
