Entanglement sharing in Jahn-Teller model in the presence of a magnetic field
G. Liberti, R. L. Zaffino, F. Piperno +1
We discuss the ground state entanglement of the Jahn-Teller model in the presence of a strong transverse magnetic field as a function of the vibronic coupling strength.…

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…

Entanglement of a qubit coupled to a resonator in the adiabatic regime
G. Liberti, R. L. Zaffino, F. Piperno +1
We discuss the ground state entanglement of a bi-partite system, composed by a qubit strongly interacting with an oscillator mode, as a function of the coupling strenght, the trans…
