| 英文摘要 | The fermionic green's function theory of heisenberg-like hamiltonian is presented in this paper. for the case that the hamiltonian is isotropic and the higher-order green's function is asymmetrically decoupled, the present theory is equivalent to the bosonic green's function theory. when the hamiltonian is anisotropic and the higher-order green's function is symmetrically decoupled, it gives the universal formula to calculate the three components of statistical average of spin operators which one encountered when dealing with ferromagnetic or ferroelectric systems described by anisotropic heisenberg model or pseudospin model respectively. both cases of |
