Abstract
We describe a new method for calculating the surface tension along a surface separating two coexisting phases. It is based on a Monte Carlo simulation where one-half of the lattice is adiabatically brought from one phase to the other. The surface free energy is obtained as a difference between the total free energies of the homogeneous and mixed phases. We present the results from a numerical simulation of the two-dimensional seven-state Potts model. Application to lattice quantum chromodynamics is also discussed.Keywords
