Van der Waals and resonance interactions between accelerated atoms in vacuum and the Unruh effect
M. Lattuca, J. Marino, A. Noto +4
We discuss different physical effects related to the uniform acceleration of atoms in vacuum, in the framework of quantum electrodynamics. We first investigate the van der Waals/Ca…
Exceptional Points in a non-Hermitian extension of the Jaynes-Cummings Hamiltonian
Fabio Bagarello, Francesco Gargano, Margherita Lattuca +3
We consider a generalization of the non-Hermitian symmetric Jaynes-Cummings {Hamiltonian, recently introduced for studying optical phenomena with time-dependent phy…
Non-thermal effects of acceleration in the resonance interaction between two uniformly accelerated atoms
Lucia Rizzuto, Margherita Lattuca, Jamir Marino +4
We study the resonance interaction between two uniformly accelerated identical atoms, one excited and the other in the ground state, prepared in a correlated (symmetric or antisymm…
Non-Hermitian Hamiltonian for a Modulated Jaynes-Cummings Model with PT Symmetry
Fabio Bagarello, Margherita Lattuca, Roberto Passante +2
We consider a two-level system such as a two-level atom, interacting with a cavity field mode in the rotating wave approximation, when the atomic transition frequency or the field…
Vacuum Casimir energy densities and field divergences at boundaries
Nicola Bartolo, Salvatore Butera, Margherita Lattuca +3
We consider and review the emergence of singular energy densities and field fluctuations at sharp boundaries or point-like field sources in the vacuum. The presence of singular ene…
