Entanglement localization by a single defect in a spin chain
Tony J. G. Apollaro, Francesco Plastina
We discuss the effect of a single diagonal defect on both the static and dynamical properties of entanglement in a spin chain. We show that entanglement localizes at the defect and…
Entanglement in One-Dimensional Spin Systems
A. Osterloh, L. Amico, F. Plastina +1
For the anisotropic XY model in transverse magnetic field, we analyze the ground state and its concurrence-free point for generic anisotropy, and the time evolution of initial Bell…
Scaling of Berry's Phase Close to the Dicke Quantum Phase Transition
Francesco Plastina, Giuseppe Liberti, Angelo Carollo
We discuss the thermodynamic and finite size scaling properties of the geometric phase in the adiabatic Dicke model, describing the super-radiant phase transition for an qubit…
Scaling behavior in the adiabatic Dicke Model
G. Liberti, F. Plastina, F. Piperno
We analyze the quantum phase transition for a set of -two level systems interacting with a bosonic mode in the adiabatic regime. Through the Born-Oppenheimer approximation, we o…
