| Abstract: | A microscopic derivation of theT 2-law for the low-temperature behavior of the condensate depletion in an interacting Bose liquid is given using the knownT=0 low-lying single-particle excitations. TheT 2-term gives no contribution to the orderT 3 in the microscopic proof of Landau'sT 3-law for the specific heat of an interacting Bose liquid. |
