Electronic Transport in Intermediate Valence Compoundsty operator which is consistent with the model assumptions is derived, and the current operator is determined via the continuity equation. The model is treated within the alloy analog approximation, using the CPA to solve the alloy problem. The static conductivity and other transport quantities are

Long Wavelength Optical Lattice Vibrations and Structural Phase Transition in Mixed a-In2s3-xSex Cryl structure and one mode behavior is evident. For x > 2.5 the a-In.Se. hexagonal phase appears and the crystals exhibit a mixed one- and two mode behavior. This abrupt change in the optical spectrum evidence a structural phase transition occurring for a concentration near x ~ 2.5.

Electronic Structure and Magnetic Properties of the TiFexCo1-X System using an extension of the coherent potential approximation. The spin susceptibility of each component is calculated taking into account the electron-electron interaction via the molecular field. The results show that the antistructure atoms for nearly ordered states can carry a local moment and cou

Electronic Densities of States and Surface Segregation in Alloysnsities of states. The alloy is described in a tight binding approximation using the moments method. A particular application to CuNi alloys is presented. A systematic prediction of surface segregation is made on the basis of the d electrons per atom ratio of the components of the alloy. A good agre

Theory of Excited States for Many-Electron Systems by Means of Variational Principles for Subspacesinciples can be applied to derive Hartree-Fock type equations for excited states. In this scheme fractional occupation numbers appear. The theory of variational principles for subspaces is used to derive Slater’s transition state theory. This is achieved by showing that there is a one to one corresp

Static Electric Field Profile in a Metal and Electroreflectanceld just within the surface of a metal. This distribution has been fitted by an analytical model and then introduced in the wave equation of the light-electric field. The resolution of this last equation with the help of the Fourier transform gives the optical surface impedance of the metal as a func

The Fictitious Equilibrium Ensemble in the Theory of Quenched Disordered Systemss equilibrium ensemble in an enlarged phase space, is re-examined. It is shown that Morita’s prescription, in its original form, is incomplete in that it leaves the free energy of the fictitious ensemble entirely undefined. A missing postulate, named the “zero mean potential condition”, is found whi
