Discovery of conjoined charge density waves in the kagome superconductor CsV3Sb5

Nature Communications, 2022
The nature of unconventional charge density wave in kagome metals is currently under intense debate. Here the authors report the coexistence of the 2 × 2 × 1 charge density wave in the kagome sublattice and the Sb 5p-electron assisted 2 × 2 × 2 charge ...

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).

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.

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.

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

A Theoretical Evaluation of the Efficiencies of Metal-Free 1,3,4-Oxadiazole Dye-Sensitized Solar Cells: Insights from Electron–Hole Separation Distance Analysis

Energies, 2022
Herein, some novel metal-free 1,3,4-oxadiazole compounds O1–O7 were evaluated for their photovoltaic properties using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations to determine if they can serve as ...

Atomic Charges and Electron Density Partitioning [PDF]

Australian Journal of Physics, 1985
Atomic charges are derived from two dissimilar methods of partitioning the electron density of diatomic molecules. The results given by both methods are similar, with the exception of those for molecules containing lithium; factors responsible for this discrepancy are explored.
