| Abstract: | Using the Jordan-Wigner transformation and cut-off approximation, the Letter studies the one-dimensional spin-1/2 XXZ double chain with z-directional uniform long-range interactions in the external magnetic field. Thermodynamic properties as the Helmholtz free energy, internal energy, specific heat and magnetization of the system are obtained. The first and second-order phase transition of the system at a finite temperature are also given. Our results agree with those of the other literatures. |
