Dirk Husmeier PhDelopment of a detailed understanding of the surface electronic structure. On the theoretical side, the general approach is similar to that for the bulk crystal: In essence the one-electron approximation is used and one tries to solve the Schrödinger equation for an electron near the surface.

Dirk Husmeier PhD.e. the dynamics of the electrons, and the lattice degrees of freedom, i.e. the dynamics of the ions, can be considered as decoupled to a good approximation. Accordingly, in Chap. 4 we only considered the lattice vibrations (phonons) and in Chap. 5 and 6 only the electrons. But we already know fromArboreal 发表于 2025-3-24 12:56:25
Dirk Husmeier PhD number representation and the description of the many-particle states and operators in terms of fermion creation and annihilation operators is explained in detail. The representation of the Hamilton operator of interacting electrons in occupation number representation (“second quantization”) is derFinasteride 发表于 2025-3-24 16:30:51
Dirk Husmeier PhDmoments can interact with each other. Specifically, the direct exchange interaction is discussed and the indirect, RKKY-interaction mediated by conduction electrons. The Heisenberg model for mutually interacting magnetic moments is treated in detail in the mean field approximation. Magnons, as the seustachian-tube 发表于 2025-3-24 19:56:44
