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…
Topology induced anomalous defect production by crossing a quantum critical point
A. Bermudez, D. Patanè, L. Amico +1
We study the influence of topology on the quench dynamics of a system driven across a quantum critical point. We show how the appearance of certain edge states, which fully charact…
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…
Bound entanglement in the XY model
D. Patané, R. Fazio, L. Amico
We study the multi-spin entanglement for the 1D anisotropic XY model concentrating on the simplest case of three-spin entanglement. As compared to the pairwise entanglement, three-…
Divergence of the entanglement range in low dimensional quantum systems
L. Amico, F. Baroni, A. Fubini +3
We study the pairwise entanglement close to separable ground states of a class of one dimensional quantum spin models. At T=0 we find that such ground states separate regions, in t…
