Journal ArticleDOI

Roles of central and terminal carbon atoms in infrared and Raman intensities of polyenes: Analysis of atomic polar and polarizability tensors

TL;DR: In this article, the role of each atom in the IR and Raman spectra of polyene derivative systems was investigated. But no theoretical and experimental information has been available for the role each atom played in polyene spectra.
Journal ArticleDOI

Counterintuitive Coulomb hole around the bond midplane

TL;DR: The Coulomb hole does not have its largest depth around an electron in or near the bond midplane, and is shown to arise from correlation effects on the one-electron density rather than correlation effects in the pair density.
Journal ArticleDOI

Machine Learning of First-Principles Force-Fields for Alkane and Polyene Hydrocarbons.

TL;DR: In this article, machine learning interatomic potentials (ML-IAPs) are generated for alkane and polyene hydrocarbons using on-the-fly adaptive sampling and a sparse Gaussian process regression (SGPR) algorithm.
Journal ArticleDOI

Anomalous behavior of mercury in one dimension: Density-functional calculations

TL;DR: In this article, the effect of reduction of dimensionality on Zn, Cd, and Hg linear chains was investigated and it was shown that Hg stands out with uncommon properties in one dimension s1Dd.
Journal ArticleDOI

Two-Dimensional Excitonic Photoluminescence in Graphene on a Cu Surface.

TL;DR: Two-dimensional excitonic photoluminescence from graphene grown on a Cu(111) surface is reported, which shows an unexpected and remarkably sharp strong emission near 3.16 eV and as temperature increases, these emissions blue shift, displaying the characteristic negative thermal coefficient of graphene.
