Density of kinks after a sudden quench in the quantum Ising spin chain
Sei Suzuki, Davide Rossini, Giuseppe E. Santoro
We investigate the time evolution of the density of kinks in the spin-1/2 quantum Ising spin chain after a sudden quench in the transverse field strength, and find that it relaxes…
Calculating Thermodynamics Properties of Quantum Systems by a non-Markovian Monte Carlo Procedure
Yanier Crespo, Alessandro Laio, Giuseppe E. Santoro +1
We present a history-dependent Monte Carlo scheme for the efficient calculation of the free-energy of quantum systems, inspired by the Wang-Landau sampling and metadynamics method.…
Adiabatic dynamics in a spin-1 chain with uniaxial single-spin anisotropy
Elena Canovi, Davide Rossini, Rosario Fazio +1
We study the adiabatic quantum dynamics of an anisotropic spin-1 XY chain across a second order quantum phase transition. The system is driven out of equilibrium by performing a qu…
Adiabatic dynamics of a quantum critical system coupled to an environment: Scaling and kinetic equation approaches
Dario Patanè, Alessandro Silva, Luigi Amico +2
We study the dynamics of open quantum many-body systems driven across a critical point by quenching an Hamiltonian parameter at a certain velocity. General scaling laws are derived…
Effective thermal dynamics following a quantum quench in a spin chain
Davide Rossini, Alessandro Silva, Giuseppe Mussardo +1
We study the nonequilibrium dynamics of the Quantum Ising Model following an abrupt quench of the transverse field. We focus on the on-site autocorrelation function of the order pa…
Adiabatic quantum dynamics of the Lipkin-Meshkov-Glick model
Tommaso Caneva, Rosario Fazio, Giuseppe E. Santoro
The adiabatic quantum evolution of the Lipkin-Meshkov-Glick (LMG) model across its quantum critical point is studied. The dynamics is realized by linearly switching the transverse…
