Bose condensation in (random) traps
We study a non-interacting (perfect) Bose-gas in random external potentials (traps). It is shown that a generalized Bose-Einstein condensation in the random eigenstates manifests if and only if the same occurs in the one-particle kinetic-energy eigenstates, which corresponds to the generalized con...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We study a non-interacting (perfect) Bose-gas in random external potentials (traps). It is shown that a generalized
Bose-Einstein condensation in the random eigenstates manifests if and only if the same occurs in
the one-particle kinetic-energy eigenstates, which corresponds to the generalized condensation of the free
Bose-gas. Moreover, we prove that the amounts of both condensate densities are equal. This statement is
relevant for justification of the Bogoliubov approximation in the theory of disordered boson systems. |
