Magnetism and Giant Magneto-Transport Properties in Granular Solids

Magnetic granular solids consist of nanometer-sized magnetic particles uniformly dispersed and embedded in an immiscible insulating or metallic medium. They display a rich variety of magnetic properties and giant magneto-transport properties due to their unique nanostructure, which can be usefully described by the metal volume fraction and the metal particle diameter of granular solids. Fabrica...

Perspective: THz-driven nuclear dynamics from solids to molecules

Recent years have seen dramatic developments in the technology of intense pulsed light sources in the THz frequency range. Since many dipole-active excitations in solids and molecules also lie in this range, there is now a tremendous potential to use these light sources to study linear and nonlinear dynamics in such systems. While several experimental investigations of THz-driven dynamics in so...

Tight-binding theory of molecules and solids

A general tight-binding analysis is described which differs from traditional methods in that 1) analytical forms are derived and utilized for obtaining the coupling parameters, and 2) the calculation of electronic-state energies is simplified sufficiently that they also can be obtained analytically. With these two features it becomes possible to write formulae for a wide range of bonding, diele...

Vibronic coupling in molecules and in solids.

We utilize the experience gained in our previous studies on the "chemistry of vibronic coupling" in simple homonuclear and heteronuclear molecules to begin assembling theoretical guidelines for the construction of potentially superconducting solids exhibiting large electron-phonon coupling. For this purpose we analyze similarities between vibronic coupling in isolated molecules and in extended ...
