Consequences of integrability breaking in quench dynamics of pairing Hamiltonians
Jasen A. Scaramazza, Pietro Smacchia, Emil A. Yuzbashyan
We study the collisionless dynamics of two classes of nonintegrable pairing models. One is a BCS model with separable energy-dependent interactions, the other - a 2D topological su…
Dynamics following a linear ramps in the model: dynamical transition and statistics of excitations
Anna Maraga, Pietro Smacchia, Alessandro Silva
Non-thermal dynamical critical behavior can arise in isolated quantum systems brought out of equilibirum by a change in time of their parameters. While this phenomenon has been stu…
Exploring dynamical phase transitions and prethermalization with quantum noise of excitations
Pietro Smacchia, Michael Knap, Eugene Demler +1
Dynamical phase transitions can occur in isolated quantum systems that are brought out of equilibrium by sudden parameter changes. We discuss the characterization of such dynamical…
Nonadiabatic stationary behaviour in a driven low-dimensional gapped system
Anna Maraga, Pietro Smacchia, Michele Fabrizio +1
We discuss the emergence of nonadiabatic behavior in the dynamics of the order parameter in a low-dimensional quantum many-body system subject to a linear ramp of one of its parame…
Work distribution and edge singularities for generic time-dependent protocols in extended systems
Pietro Smacchia, Alessandro Silva
We study the statistics of the work done by globally changing in time with a generic protocol the mass in a free bosonic field theory with relativistic dispersion and the transvers…
Universal energy distribution of quasi-particles emitted in a local time dependent quench
Pietro Smacchia, Alessandro Silva
We study the emission of quasi-particles in the scaling limit of the 1d Quantum Ising chain at the critical point perturbed by a time dependent local transverse field. We compute \…
Statistical mechanics of the Cluster-Ising model
Pietro Smacchia, Luigi Amico, Paolo Facchi +4
We study a Hamiltonian system describing a three-spin-1/2 cluster-like interaction competing with an Ising-like anti-ferromagnetic interaction. We compute free energy, spin correla…
