Finite size spectrum of SU(N) principal chiral field from discrete Hirota dynamics
Using recently proposed method of discrete Hirota dynamics for integrable (1+1)D quantum field theories on a finite space circle of length L we derive and test numerically a finite system of nonlinear integral equations for the exact spectrum of energies of SU(N)×SU(N) principal chiral field model a...
