From localization to anomalous diffusion in the dynamics of coupled kicked rotors
Simone Notarnicola, Fernando Iemini, Davide Rossini +3
We study the effect of many-body quantum interference on the dynamics of coupled periodically kicked systems whose classical dynamics is chaotic and shows an unbounded energy incre…
Dynamical Quantum Phase Transitions in Systems with Continuous Symmetry Breaking
Simon A. Weidinger, Markus Heyl, Alessandro Silva +1
Interacting many-body systems that are driven far away from equilibrium can exhibit phase transitions between dynamically emerging quantum phases, which manifest as singularities i…
Chaotic dynamical ferromagnetic phase induced by non-equilibrium quantum fluctuations
A. Lerose, J. Marino, B. Zunkovic +2
We investigate the robustness of a dynamical phase transition against quantum fluctuations by studying the impact of a ferromagnetic nearest-neighbour spin interaction in one spati…
Dynamical phase transitions, temporal orthogonality and the dynamics of observables in one dimensional ultra-cold quantum gases: from the continuum to the lattice
Thomás Fogarty, Ayaka Usui, Thomas Busch +2
We investigate the dynamics of the rate function and of local observables after a quench in models which exhibit phase transitions between a superfluid and an insulator in their gr…
Multipartite entanglement after a quantum quench
Silvia Pappalardi, Angelo Russomanno, Alessandro Silva +1
We study the multipartite entanglement of a quantum many-body system undergoing a quantum quench. We quantify multipartite entanglement through the quantum Fisher information (QFI)…
