Building an entanglement measure on physical ground
D. Teresi, A. Napoli, A. Messina
We introduce on physical grounds a new measure of multipartite entanglement for pure states. The function we define is discriminant and monotone under LOCC and moreover can be expr…
Non-Markovian dynamics of cavity losses
M. Scala, B. Militello, A. Messina +3
We provide a microscopic derivation for the non-Markovian master equation for an atom-cavity system with cavity losses and show that they can induce population trapping in the atom…
Non-Markovian dynamics of a single electron spin coupled to a nuclear spin bath
E. Ferraro, H. -P. Breuer, A. Napoli +2
We apply the time-convolutionless (TCL) projection operator technique to the model of a central spin which is coupled to a spin bath via nonuniform Heisenberg interaction. The seco…
Quantum light depolarization: the phase-space perspective
A. B. Klimov, J. L. Romero, L. L. Sanchez-Soto +2
Quantum light depolarization is handled through a master equation obtained by coupling dispersively the field to a randomly distributed atomic reservoir. This master equation is so…
Population trapping due to cavity losses
M. Scala, B. Militello, A. Messina +3
In population trapping the occupation of a decaying quantum level keeps a constant non-zero value. We show that an atom-cavity system interacting with an environment characterized…
A criterion for entanglement in two two-level systems
E. Ferraro, A. Napoli, A. Messina
We prove a necessary and sufficient condition for the occurrence of entanglement in two two-level systems, simple enough to be of experimental interest. Our results are illustrated…
