Tuning the electromagnetic local density of states in graphene-covered systems via strong coupling with graphene plasmons
Riccardo Messina, Jean-Paul Hugonin, Jean-Jacques Greffet +6
It is known that the near-field spectrum of the local density of states of the electromagnetic field above a SiC/air interface displays an intense narrow peak due to the presence o…
Graphene-based photovoltaic cells for near-field thermal energy conversion
Riccardo Messina, Philippe Ben-Abdallah
Thermophotovoltaic devices are energy-conversion systems generating an electric current from the thermal photons radiated by a hot body. In far field, the efficiency of these syste…
Unitary transfer of entanglement in multipartite two-level systems
Riccardo Messina, Anna Napoli, Antonino Messina
The dynamics of a system composed by two pairs of dipolarly coupled two-level atoms is exactly studied. We show that the initial entanglement stored in a couple of atoms not direct…
Three-body amplification of photon heat tunneling
Riccardo Messina, Mauro Antezza, Philippe Ben-Abdallah
Resonant tunneling of surface polaritons across a subwavelength vacuum gap between two polar or metallic bodies at different temperatures leads to an almost monochromatic heat tran…
Quantum systems in a stationary environment out of thermal equilibrium
Bruno Bellomo, Riccardo Messina, Didier Felbacq +1
We discuss how the thermalization of an elementary quantum system is modified when the system is placed in an environment out of thermal equilibrium. To this aim we provide a detai…
Dynamical aspects of atom interferometry in an optical lattice in proximity of a surface
Sophie Pelisson, Riccardo Messina, Marie-Christine Angonin +1
The efficiency of an atomic interferometer in proximity of a surface is discussed. We first study which is the best choice of frequency for a pulse acting on internal atomic transi…
