Spin-flip scattering of conduction electrons from impurities
… impurities on the spin orientation lifetime of conduction electrons. We have made a theoretical and experimental study of the effect of non-magnetic elemental impurities on the conduction electron spin resonance (CESR) in metals. By measuring the concentration dependence of the C~SR linewidth, …

Spin-flip scattering of conduction electrons from impurities in molten sodium
… four new impurities (Bi, Pt, Pd, and Ag) on the conduction electron spin resonance signal of sodium metal has been observed. Due to solubility problems, previous attempts to see effects from these impurities have been unsuccessful. By going into the molten state these problems were surmounted. …

Valence transition and superconductivity in the extended periodic Anderson model
… Coulomb repulsion U f c between localized f electrons and conduction electrons is investigated by use of the projector-based renormalization method (PRM). First, it is shown that the model in one dimension shows a valence transition, which becomes sharper, when the energy of the f level …

Core-valence-valence auger spectra of the simple metals
… treats the (static) screening of a core hole by conduction electrons with a phenomenological potential. Our model is applicable only to the simple metals, because free-electron theory is used to describe the conduction electrons. The model is implemented with a finite-particle, determinantal …

g-factors for ternary crystals of groups iii and v
… The g-factors were calculated for the conduction electrons, since they have the greatest contribution to the magnetic properties of the crystal. The thesis presented here proposes a method to calculate the magnetic g-factor of whole families of crystals made of three elements, of the …

Interlayer exchange coupling in magnetic multilayers
… localized magnetic moments interact weakly with conduction electrons. The other is based on spin-dependent band structures for ferromagnetic materials, which is suitable for transition metals.

Phases and phase transitions of strongly correlated electron systems
… In these systems, a lattice of localized electrons in f or d orbitals is coupled to the conduction electrons through an antiferromagnetic coupling. Singlets are formed between localized and conduction electrons. This singlet naturally have non-zero internal angular momentum. This …

Liouville resolvent methods applied to highly correlated systems
… atomic limit with the opening of a band for the conduction electrons. No phase transition was observed. A bose space calculation using the proper boson norm indicates that the conduction band induces a correlation between localized electrons on nearest-neighbor sites. It is not known if this …

Simulation methods for plasmonic structures
… produces a collective excitation of conduction electrons at the metal surface, also known as surface plasmons. These plasmonic resonances enable an unprecedented control of light by confining the electromagnetic field to regions well beyond the diffraction limit, thereby leading to …

Lattice thermal conductivity of copper alloys below 2 K
… phonons. The scattering of thermal phonons by conduction electrons below T z 1 K was found to be in good agreement with theory. A resonant interaction appears to exist between the phonons and dislocations at a resonant frequency of ~ 10^11 Hz. Several models of resonating dislocations are …

Semiconducting tin oxide thin films on glass
… resulting from the neutralization of the conduction electrons. This also causes the impurity band to shrink and show an increase in the extrinsic activation energy and near infrared transmission.

Three-particle mechanism for unconventional superconductivity with potential applications in moiré materials
… is introduced, wherein pairing between two conduction electrons is mediated by the virtual motion of a third one originating from the valence band. Relying on interband polarization rather than singularities near the Fermi level, this mechanism bypasses the limitations that other electronic …
