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…
The quantum Ising chain for beginners
Glen Bigan Mbeng, Angelo Russomanno, Giuseppe E. Santoro
We present here various techniques to work with clean and disordered quantum Ising chains, for the benefit of students and non-experts. Starting from the Jordan-Wigner transformati…
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…
