摘要：

Using the recently proposed multicanonical ensemble, we perform Monte Carlo simulations for the two-dimensional 7-state Potts model and calculate its surface free energy density (surface tension) to be 2f(s) = 0.0241 +/- 0.0010. This is an order of magnitude smaller than other estimates in the recent literature. Relying on existing Monte Carlo data, we also give a preliminary estimate for the surface tension of four-dimensional SU(3) lattice gauge theory with L(t) = 2.
