Perturbative study of the Kitaev model with spontaneous time-reversal symmetry breaking
S. Dusuel, K. P. Schmidt, J. Vidal +1
We analyze the Kitaev model on the triangle-honeycomb lattice whose ground state has recently been shown to be a chiral spin liquid. We consider two perturbative expansions: the is…
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.…
Protecting entanglement via the quantum Zeno effect
Sabrina Maniscalco, Francesco Francica, Rosa L. Zaffino +2
We study the exact entanglement dynamics of two atoms in a lossy resonator. Besides discussing the steady-state entanglement, we show that in the strong coupling regime the system-…
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…
Reply to "Comment on equivalence between quantum phase transition phenomena in radiation-matter and magnetic systems"
Giuseppe Liberti, Rosa Letizia Zaffino
A short Reply to the Comment of Brankov, Tonchev and Zagrebnov, quant-ph/0506207, is given.
Thermodynamic properties of the Dicke model in the strong-coupling regime
Giuseppe Liberti, Rosa Letizia Zaffino
We discuss the problem of a N two-level systems interacting with a single radiation mode in the strong-coupling regime. The thermodynamic properties of Dicke model are analyzed dev…
