Formulation and numerical results of the transfer-matrix method for quantum spin chains

We give a novel and explicit description of the numerical transfer-matrix method for quantum spin chains in thermal equilibrium, based on a real-space Trotter decomposition of the corresponding statistical operator. We apply the method to a spin-12 chain with a magnetic field and varying anisotropy in the nearest-neighbor exchange interaction. Some of the results are compared with exact ones which are available in limiting cases.
