Exact surface energies and boundary excitations of the Izergin-Korepin model with generic boundary fields

Year: 2025
Type: article
Abstract: A bstract The Izergin-Korepin model is an integrable model with the simplest twisted quantum affine algebra U q ( $$ {A}_2^{(2)} $$ A 2 2 ) symmetry. Applying the t - W method, we derive the homogeneous zeroes Bethe ansatz equations and the corresponding zeroes patterns of the Izergin-Korepin model with generic integrable boundaries. Based on these results, we analytically compute the surface energies and boundary excitations in different regimes of boundary parameters of the model. It is shown that in some regimes, correlation effect appears between two boundary fields.
