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…
Next Nearest-Neighbor Correlation Functions of the Spin-1/2 XXZ Chain at Massive Region
Minoru Takahashi, Go Kato, Masahiro Shiroishi
The second neighbor correlation functions of the spin- chain in the ground state are expressed in the form of three dimensional integrals. We show that these integrals…
Graphical representation of the partition function for a 1-D delta-function Bose gas
Go Kato, Miki Wadati
One-dimensional repulsive delta-function bose system is studied. By only using the Bethe ansatz equation, n-particle partition functions are exactly calculated. From this expressio…
Partition Function for a 1-D delta-function Bose Gas
Go Kato, Miki Wadati
The N-particle partition function of a one-dimensional -function bose gas is calculated explicitly using only the periodic boundary condition (the Bethe ansatz equation). The N-…
