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…
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…
Evaluation of Dynamic spin structure factor for the spin-1/2 XXZ chain in a magnetic field
Jun Sato, Masahiro Shiroishi, Minoru Takahashi
Transition rates and dynamic spin structure factor at zero temperature for the spin-1/2 XXZ chain at critical regime in a magnetic field are numerically evaluated in terms of the e…
