Abstract

Thermodynamic quantities such as specific heat, magnetization, magnetic susceptibility for the spin 1/2 quantum anisotropic Heisenberg chain in the presence of a longitudinal magnetic field will be obtained by the numerical diagonalization of the associated Hamiltonian on one-dimensional finite systems.
