Many Body Interactions – Introductionctron gas and spin density wave states in solids. Equation of motion method is considered for density matrix to describe gauge invariant theory of linear responses in the presence of the most general electromagnetic disturbance. Behavior of Lindhard dielectric functions and static screening effects

Many Body Interactions: Green’s Function Methodt of time ordered Heisenberg operators in the exact interacting ground state. We then introduce the interaction representation of the state functions of many particle states and write the Green’s function in terms of time ordered products of interaction operators. Wick’s theorem is introduced to wri

Semiclassical Theory of Electronse discussed, and simple two band model of magnetoresistance is illustrated including the effect of collisions. General expression of semiclassical mag- netoconductivity tensor is derived by solving the Boltzmann equation of the distribution function, and the results are applied to the case of free e

More Band Theory and the Semiclassical Approximations practical alternative ways of including the effects of periodic symmetry of crystal potential. Then, the semiclassical wave packet picture is discussed to describe the motion of the Bloch electrons in a given band. In addition, ideas of effective mass and hole are shown to be convenient in describing the behavior of band electrons.

Magnetic Ordering and Spin Wavesand antiferromagnets are described. Spin wave excitations and magnon heat capacities of ferromagnets and antiferromagnets are also discussed. Finally, Stoner model is introduced as an illustration of itinerant ferromagnetism.
