INTRODUCTION: Density functional theory (DFT) is a widely used method for calculating the electronic properties of materials. The method is based on the idea of approximating the many-electron wave ...
Researchers at the University of Illinois Urbana-Champaign have detected the existence of a charge density wave of electrons that acquires mass as it interacts with the background lattice ions of the ...
Charge-density waves (CDWs) are ubiquitous in underdoped cuprate superconductors. As a modulation of the valence electron density, CDWs in hole-doped cuprates possess both Cu-3d and O-2p orbital ...
