Exact treatment of operator difference equations with nonconstant noncommutative coefficients
M. A. Jivulescu, A. Messina
In this paper we study in a Hilbert space a homogeneous linear second order difference equation with nonconstant and noncommuting operator coefficients. We build its exact resoluti…
On the merit of a Central Limit Theorem-based approximation in statistical physics
Bruno Leggio, Oleg Lychkovskiy, Antonino Messina
The applicability conditions of a recently reported Central Limit Theorem-based approximation method in statistical physics are investigated and rigorously determined. The failure…
Tripartite thermal correlations in an inhomogeneous spin-star system
F. Anzà, B. Militello, A. Messina
We exploit the tripartite negativity to study the thermal correlations in a tripartite system, that is the three outer spins interacting with the central one in a spin-star system.…
Genuine Tripartite Entanglement in a Spin-Star Network at Thermal Equilibrium
B. Militello, A. Messina
In a recent paper [M. Huber {\it et al}, Phys. Rev. Lett. {\bf 104}, 210501 (2010)] new criteria to find out the presence of multipartite entanglement have been given. We exploit t…
Stimulated Raman adiabatic passage in a -system in the presence of quantum noise
M. Scala, B. Militello, A. Messina +1
We exploit a microscopically derived master equation for the study of STIRAP in the presence of decay from the auxiliary level toward the initial and final state, and compare our r…
N-qubit states as points on the Bloch sphere
H. Mäkelä, A. Messina
We show how the Majorana representation can be used to express the pure states of an N-qubit system as points on the Bloch sphere. We compare this geometrical representation of N-q…
Dissipation and entanglement dynamics for two interacting qubits coupled to independent reservoirs
Matteo Scala, Rosanna Migliore, Antonino Messina
We derive the master equation of a system of two coupled qubits by taking into account their interaction with two independent bosonic baths. Important features of the dynamics are…
Generating and Revealing a Quantum Superposition of Electromagnetic Field Binomial States in a Cavity
R. Lo Franco, G. Compagno, A. Messina +1
We introduce the -photon quantum superposition of two orthogonal generalized binomial states of electromagnetic field. We then propose, using resonant atom-cavity interactions,…
Decoherence and robustness of parity-dependent entanglement in the dynamics of a trapped ion
S. Maniscalco, A. Messina, A. Napoli +1
We study the entanglement between the 2D vibrational motion and two ground state hyperfine levels of a trapped ion, Under particular conditions this entanglement depends on the par…
