| 英文摘要 | We present the results of a one-loop calculation of the effect of a van der Waals type interaction potential similar to\x\(-d-sigma) on the critical Casimir force and specific heat of confined He-4 near the superfluid transition. We consider a He-4 film of thickness L. In the region Lgreater than or similar toxi (correlation length) we find that the van der Waals interaction causes a leading non-universal non-scaling contribution of O(xi(2) L-d-sigma) to the critical temperature dependence of the Casimir force above T-lambda that dominates the universal scaling contribution similar toe(-L/xi) predicted by earlier theories. For the specific heat we find subleading non-scaling contributions of O(L-1) and O(L-d-sigma). (C) 2003 Elsevier Science B.V. All rights reserved. |
