Description

We use effective string theory (EST) to describe a toroidal 2d interface embedded in a 3d torus.
In particular, we compute the free energy of the interface in an expansion in inverse powers of the area, up to the first non-universal order that involves the Wilson coefficient $\gamma_3$.

In order to test our predictions, we simulate the 3d Ising model with an anti-periodic boundary condition with a two-step multicanonical algorithm that delivers high-precision free-energy data.
