Molecular Field Method and Perturbation Theory,all formulate a principle which will then be used to deduce the molecular field equations. In concluding this chapter, we shall consider the simplest variant of the perturbation theory for high temperatures.

手术刀

,Green’s Function Method,tion of transport coefficients, such as the electrical conductivity, susceptibility, etc. The results obtained are applicable to a wide range of temperatures. We shall give below the basic information about Green’s functions, and we shall develop the mathematical apparatus necessary for the solving of actual problems.

Applications of the Method of Approximate Second Quantization,In the present chapter, we consider the examples of an isotropic ferromagnet and an isotropic antiferromagnet; we shall calculate their spectra of elementary excitations and their magnetizations as a function of the temperature and the external magnetic field. In the concluding part, some further applications of the method will be indicated.

Spin Hamiltonians,are quadratic with respect to the second quantization operators). We shall also discuss the conditions under which the exact Hamiltonian of a system can be reduced to a spin Hamiltonian of the Heisenberg type, and we shall consider typical spin Hamiltonians.
