Fano-Hopfield model and photonic band gaps for an arbitrary atomic lattice
Mauro Antezza, Yvan Castin
We study the light dispersion relation in a periodic ensemble of atoms at fixed positions in the Fano-Hopfield model (the atomic dipole being modeled with harmonic oscillators). Co…

Ground state energy of the two-dimensional weakly interacting Bose gas: First correction beyond Bogoliubov theory
Christophe Mora, Yvan Castin
We consider the grand potential of a two-dimensional weakly interacting homogeneous Bose gas at zero temperature. Building on a number-conserving Bogoliubov method for a lattic…
