Abstract

In the introduction, definition of Hamiltonian (Relativistic & Non-Relativistic),  Euler’s equation and Schrodinger’s time dependent equation are used. Hamiltonian  field theory (given by Pruskin) is used Anderson Model and Jacobian  Transformation are applied. Perturbation and Green function are used. Dimmock  Hamiltonian, Dugaev and Litvinov spins (S1 and S2) are used. Heff. in  ( ) P M A A T ,S ,S b n e e −= is obtained. Various temperature and band parameters for  1 x x P M T b n e − 1 x x for x = 0.1 & x = 0.01 are listed in table.
