Electronic and Structural Fingerprints of Charge-Density-Wave Excitations in Extreme Ultraviolet Transient Absorption Spectroscopy

Physical Review X, 2023
Femtosecond core-level transient absorption spectroscopy is utilized to investigate photoinduced dynamics of the charge density wave in 1T-TiSe_{2} at the Ti M_{2,3} edge (32–50 eV).

Doublonlike Excitations and Their Phononic Coupling in a Mott Charge-Density-Wave System

Physical Review X, 2021
Electron-phonon-driven charge-density waves can in some circumstances allow electronic correlations to become predominant, driving a system into a Mott insulating state.

Melting Point Of Metals In Relation Io Electron Charge Density

Archives of Metallurgy and Materials, 2015
The concept of spatial criterion of the electron charge concentration is applied to determine the metal melting point. Based on the model proposed for bcc metals, a model for hcp metals and general form for others has been developed.

Electron Density Distributions and Atomic Charges [PDF]

Zeitschrift für Naturforschung A, 1993
Abstract Accurate electron densities and X-ray form factors of Li, Be, F and their ions have been calculated. Electron correlation, crystal fields and ionic charge transfer change the form factors by up to a few percent, mainly in the range of sin θ/ λ < 1/3 Â -1 .

Bulk charge density wave and electron-phonon coupling in superconducting copper oxychlorides

Physical Review Research, 2022
Bulk charge density waves are now reported in nearly all high-temperature superconducting cuprates, with the noticeable exception of one particular family: the copper oxychlorides. Here, we used resonant inelastic x-ray scattering to reveal a bulk charge
