Statistical field theory for liquid vapor interface | | V. Russier
; Jean-Michel Caillol
; | | Date: |
27 Nov 2009 | | Abstract: | A statistical field theory for an inhomogeneous liquid, a planar liquid/vapor
interface, is devised from first principles. The grand canonical partition
function is represented via a Hubbard-Stratonovitch tranformation leading,
close to the critical point, to the usual $phi^4$ scalar field theory which is
then rigorously considered at the one-loop level. When further simplified it
yields the well-known capillary wave theory without any ad hoc phenomenological
parameter. Internal coherence of the one-loop approximation is discussed and
good overall qualitative agreement with recent numerical simulations is
stressed. | | Source: | arXiv, 0911.5275 | | Services: | Forum | Review | PDF | Favorites | |
