Breakdown of adiabaticity in topological quantum liquids
Carola Ciaramelletti, Daniel Arrufat-Vicente, Simone Paganelli +1
We study the temporal behavior of topological quantum fluids with strong long-range couplings under slow external perturbations, whose rate approaches the quasi-static limit $δ…

Ensemble Inequivalence in Long-Range Quantum Spin Systems
Daniel Arrufat-Vicente, David Mukamel, Stefano Ruffo +1
Ensemble inequivalence occurs when a systems thermodynamic properties vary depending on the statistical ensemble used to describe it. This phenomenon is known to happen in systems…

Freezing and Shielding under Global Quenches for Long-Range Interacting Many-Body Systems
Daniel Arrufat-Vicente, Nicolò Defenu
We investigate the time evolution of a Fermi-Hubbard model with long range hopping following a sudden quench of the local interactions among different spin species. The quasi-parti…
