Density matrix elements and entanglement entropy for the spin-1/2 XXZ chain at =1/2
Jun Sato, Masahiro Shiroishi
We have analytically obtained all the density matrix elements up to six lattice sites for the spin-1/2 Heisenberg XXZ chain at . We use the multiple integral formula of the…
String correlation functions of the spin-1/2 Heisenberg XXZ chain
Michael Bortz, Jun Sato, Masahiro Shiroishi
We calculate certain string correlation functions, originally introduced as order parameters in integer spin chains, for the spin-1/2 XXZ Heisenberg chain at zero temperature and i…
Exact evaluation of density matrix elements for the Heisenberg chain
Jun Sato, Masahiro Shiroishi, Minoru Takahashi
We have obtained all the density matrix elements on six lattice sites for the spin-1/2 Heisenberg chain via the algebraic method based on the quantum Knizhnik-Zamolodchikov equatio…
Correlation functions of the spin-1/2 anti-ferromagnetic Heisenberg chain: exact calculation via the generating function
Jun Sato, Masahiro Shiroishi, Minoru Takahashi
Analytical expressions of some of the spin-spin correlation functions up to eight lattice sites for the spin-1/2 anti-ferromagnetic Heisenberg chain at zero temperature without mag…
Fifth-neighbor spin-spin correlator for the anti-ferromagnetic Heisenberg chain
Jun Sato, Masahiro Shiroishi
We study the generating function of the spin-spin correlation functions in the ground state of the anti-ferromagnetic spin-1/2 Heisenberg chain without magnetic field. We have foun…
High temperature expansion of emptiness formation probability for isotropic Heisenberg chain
Zengo Tsuboi, Masahiro Shiroishi
Recently, Göhmann, Klümper and Seel have derived novel integral formulas for the correlation functions of the spin-1/2 Heisenberg chain at finite temperature. We have found that th…
