Abstract

Using the mean-field Jordan-Wigner transformation,this paper studies the one-dimensional spin-Heisenberg XYZ antiferromagnetic chain with uniform long-range interactions among the z components of the spins in the transverse field.The research has obtained such analytic expressions and the numerical results of the thermodynamic quantities,as the Helmholtz free energy,internal energy,specific heat,magnetization and susceptibility.The results in the degenerate condition agree with that from other literatures

Using the mean-field Jordan-Wigner transformation analysis, we have studied the one-dimensional spin-1/2 XY chain with Z-directional uniform long-range interactions in the external magnetic field. We have obtained such results as the Helmholtz free energy, internal energy, specific heat, magnetization and isothermal susceptibility. We also discuss the first and second-order phase transitions of the system at a finite temperature. Our results agree with results published in literature.
