Theory of condensates in superfluids |
| abstract |
A gauge-symmetry-breaking parameter associated with the fluctuation of the zero-mode particles renders a source term to the continuity equation of interacting Bose systems. As a consequence, additional terms appear in the generalized Ward identities, which modify in an essential way the relation between the superfluid and condensate densities. An energy gap results as a function of the symmetry-breaking parameter and interatomic potential. The general results are worked out in the shielded potential approximation, and an equation for the condensate fraction n0(T) is obtained in closed form. At absolute zero the condensate fractions in dilute Bose systems and superfluid He4 are found to be n0=0.438 and n0=0.126, respectively. |

An energy gap results as a function of the symmetry-breaking parameter and interatomic potential. The general results are worked out in the shielded potential approximation, and an equation for the condensate fraction n0(T) is obtained in closed form. At absolute zero the condensate fractions in dilute Bose systems and superfluid He4 are found to be n0=0.438 and n0=0.126, respectively.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">APS Digital Backfile Archive 1893-2003</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Olinto, A.
