Modeling core-hole screening in jellium clusters using density functional theory
Modeling core-hole screening jellium clusters density functional theory
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...
Direct imaging of thermally excited metastable structures of ion Coulomb clusters
Direct imaging thermally excited metastable structures ion Coulomb clusters
2012/2/28
Coulomb crystallisation of large ensembles of ions has in the past years been intensively studied experimentally with many spectacular results of relevance to infinite systems in one-, two-, and three...
A fast Variational Gaussian Wave-packet method: Size-induced structural transitions in large neon clusters
Variational Gaussian Wave-packet method Size-induced structural transitions large neon clusters
2011/8/17
Abstract: The Variational Gaussian wavepacket (VGW) method is an alternative to Path Integral Monte-Carlo (PIMC) for the computation of thermodynamic properties of many-body systems at thermal equilib...
Observation of (N2)2 dimers in free nitrogen and argon-nitrogen clusters
(N2)2 dimers free nitrogen argon-nitrogen clusters
2011/8/4
Abstract: Supersonic-jet luminescence spectroscopy was applied to study vibronic transitions in icosahedral N2 and Ar-N2 clusters having from 100 to 400 particles per cluster. In the case of mixed Ar-...
In this work we investigate small clusters of helium atoms using the hyperspherical harmonic basis. We consider systems with A = 2, 3, 4, 5, 6 atoms with an inter-particle potential which does not pre...
Size-, shape-, and composition-dependent polarizabilities of SimCn (m, n = 1 - 4) clusters
Size shape
2011/8/30
We theoretically investigate the size-, shape-, and composition-dependent polarizabilities of the SimCn (m, n = 1 – 4) clusters by using the density functional based coupled perturbed Hartree-Fock met...
