Query: A grand-canonical approach to the disordered Bose gas   We study the problem of disordered interacting bosons within grand-canonical
thermodynamics and Bogoliubov theory. We compute the fractions of condensed and
non-condensed particles and corrections to the compressibility and the speed of
sound due to interaction and disorder. There are two small parameters, the
disorder strength compared to the chemical potential and the dilute-gas
parameter.
