Liouvillian gap and out-of-equilibrium dynamics of a sunburst Kitaev ring: from local to uniform dissipation
Alessio Franchi, Francesco Tarantelli
We consider an open quantum system composed of a -dimensional Kitaev ring coupled with the environment via particle-loss dissipators in a \textit{sunburst} geometry. We…
Chiral critical behavior of 3D lattice fermionic models with quartic interactions
Claudio Bonati, Alessio Franchi, Andrea Pelissetto +1
We study the critical behavior of the three-dimensional (3D) Gross-Neveu (GN) model with Dirac fermionic flavors and quartic interactions, at the chiral trans…
Quantum critical behaviors and decoherence of weakly coupled quantum Ising models within an isolated global system
Alessio Franchi, Andrea Pelissetto, Ettore Vicari
We discuss the quantum dynamics of an isolated composite system consisting of weakly interacting many-body subsystems. We focus on one of the subsystems, S, and study the dependenc…
Decoherence and energy flow in the sunburst quantum Ising model
