A grand-canonical approach to the disordered Bose gas

关键词:

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