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…
Thermalization dynamics close to a quantum phase transition
Dario Patanè, Alessandro Silva, Fernando Sols +1
We investigate the dissipative dynamics of a quantum critical system in contact with a thermal bath. In analogy with the standard protocol employed to analyze aging, we study the r…
Quantum instability and edge entanglement in a quasi-long-range order
Wonmin Son, Luigi Amico, Francesco Plastina +1
We investigate the build-up of quasi-long-range order in the XX chain with transverse magnetic field at finite size. As the field is varied, the ground state of the system displays…
Adiabatic dynamics in open quantum critical many-body systems
Dario Patanè, Alessandro Silva, Luigi Amico +2
The purpose of this work is to understand the effect of an external environment on the adiabatic dynamics of a quantum critical system. By means of scaling arguments we derive a ge…
