full - core atoms

Curvilinear coordinates, first introduced by F. Gygi for valence-only electronic systems within the local-density functional theory, can be used to describe both core and valence electrons in electronic-structure calculations. A simple and quite general coordinate transformation results in a large, yet affordable plane-wave energy cutoff for full-core systems (e.g., ≃ 120 Ryd for carbon or sili...

TOPOLOGY OPTIMIZATION OF STRUCTURES UNDER TRANSIENT LOADS

In this article, an efficient methodology is presented to optimize the topology of structural systems under transient loads. Equivalent static loads concept is used to deal with transient loads and to solve an alternate quasi-static optimization problem. The maximum strain energy of the structure under the transient load during the loading interval is used as objective function. The objective f...

Electron Collisional Broadening of Isolated Lines from Multiply-ionized Atoms

Recent experimental and theoretical (both improved semiclassical and fully quantum-mechanical) line broadening calculations for B III and NeVII ∆n = 0 transitions with n = 2 and 3, respectively, are discussed. The disagreements by about a factor of 2 between the fully quantum-mechanically calculated and both measured and semiclassically calculated widths can be explained in terms of violations ...
