Floquet time crystals in clock models
Federica Maria Surace, Angelo Russomanno, Marcello Dalmonte +3
We construct a class of period--tupling discrete time crystals based on clock variables, for all the integers . We consider two classes of systems where this p…
Quasi-localized excitations induced by long-range interactions in translationally-invariant quantum spin chains
Alessio Lerose, Bojan Zunkovic, Alessandro Silva +1
We show that long-range ferromagnetic interactions in quantum spin chains can induce spatial quasi-localization of topological magnetic defects, i.e., domain-walls, even in the abs…
Coherent Impurity Transport in an Attractive Binary Bose-Einstein condensate
M. J. Edmonds, J. L. Helm, Th. Busch
We study the dynamics of a soliton-impurity system modeled in terms of a binary Bose-Einstein condensate. This is achieved by `switching off' one of the two self-interaction scatte…
Impact of non-equilibrium fluctuations on pre-thermal dynamical phase transitions in long-range interacting spin chains
Alessio Lerose, Bojan Zunkovic, Jamir Marino +2
We study the non-equilibrium phase diagram and the dynamical phase transitions occurring during the pre-thermalization of non-integrable quantum spin chains, subject to either quan…
Scrambling and entanglement spreading in long-range spin chains
Silvia Pappalardi, Angelo Russomanno, Bojan Žunkovič +3
We study scrambling in connection to multipartite entanglement dynamics in regular and chaotic long-range spin chains, characterized by a well defined semi-classical limit. For reg…
The role of quantum work statistics in many-body physics
John Goold, Francesco Plastina, Andrea Gambassi +1
In this contribution, we aim to illustrate how quantum work statistics can be used as a tool in order to gain insight on the universal features of non-equilibrium many-body systems…
