One-Dimensional Hubbard Model at Finite Temperature

Minoru Takahashi

Published Jan 1, 1972• 265 citations
Publisher

Abstract

The method of integral equations with infinitely many unknowns which were used for the one-dimensional Heisenberg model and electron gas is applied to the one-dimensional Hubbard model. From these equations one can calculate energy, entropy, density and magnetization at given temperature, chemical potential and magnetic field.

One-Dimensional Heisenberg Model at Finite Temperature

Minoru Takahashi

A set of integral equations which describes the thermodynamic properties of one-dimensional Heisenberg model is obtained. From these equations one can calculate the energy, entropy and magnetization of the system at given temperature and magnetic field. We have succeeded in reproducing the known exact results in the limiting cases of zero temperature, infinite temperature and infinite magnetic field.

Thermodynamic properties of one-dimensional hubbard model at finite temperatures

Yang C; Kocharian AN; Chiang YL

[[abstract]]The phase diagram and thermodynamic properties of the Hubbard model in one dimension are calculated numerically within the generalized self-consistent approach over a wide range of temperature T, magnetic field h, interaction strength U/t and electron concentration n. The temperature variation of the transverse magnetization, double occupied sites and chemical potential at various n, U/t and h is also analyzed. The wave vector q for the magnetic order parameter in the vicinity of the half-filling in the metallic phase shows a crossover from incommensurate magnetic phase (0 < q < pi) into the state with strong antiferromagnetic correlations (q = pi) as temperature is increased. Overall our numerical results in the approximate theory at finite temperatures are in good quantitative and qualitative agreement with the Bethe-ansatz results.
