Third-neighbor and other four-point correlation functions of spin-1/2 XXZ chain

Go Kato, Masahiro Shiroishi, Minoru Takahashi +1

The correlation functions of the spin-1/2 XXZ chain in the ground state were expressed in the form of multiple integrals for -1<Δ\leq 1 and 1<Δ. In particular, adjacent four-point…
