Exactness of the Bogoliubov approximation in random external potentials
Thomas Jaeck, Valentin Zagrebnov
We investigate the validity of the Bogoliubov c-number approximation in the case of interacting Bose-gas in a \textit{homogeneous random} media. To take into account the possible o…

On the nature of Bose-Einstein condensation enhanced by localization
Thomas Jaeck, Joseph V. Pulé, Valentin Zagrebnov
In a previous paper we established that for the perfect Bose gas and the mean-field Bose gas with an external random or weak potential, whenever there is generalized Bose-Einstein…

On the nature of Bose-Einstein condensation in disordered systems
Thomas Jaeck, Joseph V. Pulé, Valentin Zagrebnov
We study the perfect Bose gas in random external potentials and show that there is generalized Bose-Einstein condensation in the random eigenstates if and only if the same occurs i…
