Strongly Correlated Electrons in Solids
Most emergent properties of the materials discovered since the 1980s are related to the existence of electronelectron interactions which are large with respect to the kinetic energies and could not be thoroughly studied before. The occurrence of metal insulator transitions, of exotic magnetic and/or superconducting properties in many new compounds have stimulated a large series of experimental ...
متن کاملTheories on Frustrated Electrons in Two-Dimensional Organic Solids
Two-dimensional quarter-filled organic solids are a promising class of materials to realize the strongly correlated insulating states called dimer Mott insulator and charge order. In their conducting layer, the molecules form anisotropic triangular lattices, harboring geometrical frustration effect, which could give rise to many interesting states of matter in the two insulators and in the meta...
متن کاملCloaking core-shell nanoparticles from conducting electrons in solids.
In this Letter, we aim at making nanoparticles embedded in a host semiconductor with a size comparable to electronic wavelengths "invisible" to the electron transport. Inspired by the recent progress made in optics and working within the framework of the expansion of partial waves, we demonstrate that the opposite effects imposed by potential barriers and wells of a core-shell nanoparticle on t...
متن کاملIonization by impact electrons in solids: Electron mean free path fitted over a wide energy range
We propose a simple formula for fitting the electron ionization mean free paths in solids both at high and at low electron energies. The free-electron-gas approximation used for predicting electron mean free paths is no longer valid at low impact energies E−EF 50 eV , as the band structure effects become significant at those energies. Therefore, we include the results of band structure calculat...
متن کاملLasers Emerge as a Tool for the Direct Study of Electrons in Solids
A ngle-resolved photoemission spectroscopy is the most direct way to observe the quantum-mechanical structure of electrons in solids and one of the key tools used to understand the complex electronic interactions that lead to high-temperature superconductivity.1 In these experiments, high-energy photons eject electrons from the material of interest. Because the electron momentum is conserved in...
