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…
Completely Positive Maps for Reduced States of Indistinguishable Particles
Leonardo da Silva Souza, Tiago Debarba, Diego L. Braga Ferreira +2
We introduce a framework for the construction of completely positive maps for subsystems of indistinguishable fermionic particles. In this scenario, the initial global state is alw…
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…
Non-topological parafermions in a one-dimensional fermionic model with even multiplet pairing
Leonardo Mazza, Fernando Iemini, Marcello Dalmonte +1
We discuss a one-dimensional fermionic model with a generalized even multiplet pairing extending Kitaev chain. The system shares many features wit…
