The partition function of the four-vertex model in a special external field
N. Bogoliubov, C. Malyshev St. Petersburg Department of Steklov Institute of Mathematics, RAS, Fontanka 27, St. Petersburg, Russia
Abstract:
The exactly solvable four-vertex model on a square grid with the fixed boundary conditions in a presence of a special external field is considered. Namely, we study a system in a linear field acting on the central column of a grid. The partition function of the model is calculated by Quantum Inverse Scattering Method. The answer is written in the determinantal form.
Key words and phrases:
four-vertex model, integrable models, Quantum Inverse Scattering Method.
