Impact of Pre-Patterned Structures on Features of Laser-Induced Periodic Surface Structures

Molecules, 2021
The efficiency of light coupling to surface plasmon polariton (SPP) represents a very important issue in plasmonics and laser fabrication of topographies in various solids. To illustrate the role of pre-patterned surfaces and impact of laser polarisation

Electronic Structure of Hyperkagome Na4Ir3O8

, 2010
We investigate the electronic structure of the frustrated magnet Na4Ir3O8 using density functional theory. Due to strong spin-orbit coupling, the hyperkagome lattice is characterized by a half-filled complex of states, making it a cubic iridium analogue ...

Electronic Structure of Ladder Cuprates

, 1998
We study the electronic structure of the ladder compounds (SrCa)CuO 14-24-41 and SrCuO 123. LDA calculations for both give similar Cu 3d-bands near the Fermi energy.

A Transferable Machine-Learning Model of the Electron Density [PDF]

, 2018
The electronic charge density plays a central role in determining the behavior of matter at the atomic scale, but its computational evaluation requires demanding electronic-structure calculations. We introduce an atom-centered, symmetry-adapted framework
