Abstract
摘要 |
Exactly solvable models have provided some important benchmarks for the non-perturbative analysis of quantum systems. However, it has been well known for many years that there exists a quite unusual class of integrable models, which do not possess U(1)-symmetry and thus make the conventional Bethe ansatz methods almost inapplicable. Recently a systematic method for solving integrable models without U(1)-symmetry, i.e., the off-diagonal Bethe ansatz (ODBA) method was proposed by Cao et al. Using this method, we solve various typical U(1)-broken quantum spin chains with general integrable boundary condition. |
