Entanglement, BEC, and superfluid-like behavior of two-mode photon systems
Ferdinando de Pasquale, Gian Luca Giorgi
A system of two interacting photon modes, without constraints on the photon number, in the presence of a Kerr nonlinearity, exhibits BEC if the transfer amplitude is greater than t…

Quantum phase diffusion of a Bose system: beyond the Hartree-Fock-Bogoliubov approximation
Ferdinando de Pasquale, Gian Luca Giorgi
A diffusion process is usually assumed for the phase of the order parameter of a Bose system of finite size. The theoretical basis is limited to the so called Bogoliubov approximat…
