Exact ground state and elementary excitations of a topological spin chain

28 Sep 2020 Qiao Yi Sun Pei Cao Junpeng Yang Wen-Li Shi Kangjie Wang Yupeng

A novel Bethe Ansatz scheme is proposed to calculate physical properties of quantum integrable systems without $U(1)$ symmetry. As an example, the anti-periodic XXZ spin chain, a typical correlated many-body system embedded in a topological manifold, is examined... (read more)
