Abstract
Monte Carlo simulations have been used to calculate the surface tension
of a planar liquid-vapour interface of a Lennard-Jones fluid using a new
cylindrical truncation correction procedure. A bubble was mimicked by
simulating a Lennard-Jones liquid close to coexistence containing a
single immobile hard sphere cavity. From the density profile of this
system the curvature dependent surface tension has been estimated via
calculation of the Helmholtz free energy of the system and separately
using a large cavity contact density expansion. Evidence is presented
that the Tolman length becomes increasingly negative as the critical
temperature is approached and possibly changes sig
