Numerical Investigation of the Interface Tension in the three-dimensional Ising Model
Sabine Klessinger, Gernot Muenster
Abstract
The interface tension in the three-dimensional Ising model in the low temperature phase is investigated by means of the Monte Carlo method. Together with other physically relevant quantities it is obtained from a calculation of time-slice correlation functions in a cylindrical geometry. The results at three different values of the temperature are compared with the predictions from a semiclassical approximation in the framework of renormalized ϕ4 theory in three dimensions, and are in good agreement with them.
