Fragility to quantum fluctuations of classical Hamiltonian period doubling
Reyhaneh Khasseh, Angelo Russomanno, Rosario Fazio
We add quantum fluctuations to a classical period-doubling Hamiltonian time crystal, replacing the classical interacting angular momenta with quantum spins of size . The ful…
Chaos and subdiffusion in the infinite-range coupled quantum kicked rotors
Angelo Russomanno, Michele Fava, Rosario Fazio
We map the infinite-range coupled quantum kicked rotors over an infinite-range coupled interacting bosonic model. In this way we can apply exact diagonalization up to quite large s…
Quantum chaos and ensemble inequivalence of quantum long-range Ising chains
Angelo Russomanno, Michele Fava, Markus Heyl
We use large-scale exact diagonalization to study the quantum Ising chain in a transverse field with long-range power-law interactions decaying with exponent . We numerically st…
Non-ergodic behaviour of clean Bose-Hubbard chains
Angelo Russomanno, Michele Fava, Rosario Fazio
We study ergodicity breaking in the clean Bose-Hubbard chain for small hopping strength. We see the existence of a non-ergodic regime by means of indicators as the half-chain entan…
Discrete truncated Wigner approach to dynamical phase transitions in Ising models after a quantum quench
Reyhaneh Khasseh, Angelo Russomanno, Markus Schmitt +2
By means of the discrete truncated Wigner approximation we study dynamical phase transitions arising in the steady state of transverse-field Ising models after a quantum quench. St…
Quantum clock models with infinite-range interactions
Adu Offei-Danso, Federica Maria Surace, Fernando Iemini +2
We study the phase diagram, both at zero and finite temperature, in a class of models with infinite range interactions. We are able to identify the transitions betwe…
