Exact solution and pair correlation functions for a generalized three-chain Ising tube with multispin interactions
Pavel Khrapov, Nikita Volkov
We obtain an exact solution for a generalized three-chain Ising tube (TCGIT) of length with toroidal boundary conditions and the most general -invariant Hamiltonian on an…

Exact solution of generalized triple Ising chains with multi-spin interactions
Pavel Khrapov, Nikita Volkov
We obtain the exact physical characteristics of the triple-chain Ising model on a torus with all possible multispin interactions invariant with respect to rotation by the angle $2π…
