Exact coefficients of finite-size corrections in the Ising model with Brascamp-Kunz boundary conditions and their relationships for strip and cylindrical geometries

Nikolay Sh. Izmailian, Ralph Kenna, Vladimir V. Papoyan

We derive exact finite-size corrections for the free energy $F$ of the Ising model on the $\mathcal{M}\times 2\mathcal{N}$ square lattice with Brascamp-Kunz boundary conditions. We cal…
