Big bang methodology applied to atomic clusters
(2011)
An implementation of a novel strategy for cluster geometry optimization, using a stochastic method, is applied. This algorithm is based on the spirit of Big Bang theory. The strategy consists on a three-step procedure; a ...
Ferromagnetic bond of Li-10 cluster: An alternative approach in terms of effective ferromagnetic sites
(2016)
In this work, a model to explain the unusual stability of atomic lithium clusters in their highest spin multiplicity is presented and used to describe the ferromagnetic bonding of high-spin Li-10 and Li-8 clusters. The ...
A 3D Voronoi+Gapper Galaxy Cluster Finder in Redshift Space to z ∼ 0.2. II. An Abundant Cluster Population Dominated by Late-type Galaxies Unveiled
(IOP, 2020)
We identify 1901 galaxy clusters (N-g >= 2) with the VoML+G algorithm (Paper I) on the Two-Degree Field Galaxy Redshift Survey. We present the 341 clusters with at least 10 galaxies that are within 0.009 < z < 0.14 (the ...
Modified genetic algorithms to model atomic cluster structures: CuSi clusters
(ELSEVIER, 2004-07-26)
This paper presents the results obtained using a genetic algorithm (GA) to search for stable structures of Cu-silicon clusters. In this work the GA uses a semiempirical energy function to find the best cluster structures, ...
The magellanic bridge cluster NGC 796: deep optical AO imaging reveals the stellar content and initial mass function of a massive open cluster
(IOP Publishing Ltd, 2018)
NGC 796 is a massive young cluster located 59 kpc from us in the diffuse intergalactic medium of the 1/5-1/10 Z(circle dot) Magellanic Bridge, allowing us to probe variations in star formation and stellar evolution processes ...
Density functional theory characterization of the formation of copper clusters on Fs and Fs+ centers on a MgO surface
(2007)
Electronic structure and chemical reactivity of Cun clusters (n = 1-4) supported on a regular site (O5c) and on an oxygen vacancy (Fs and Fs+) of the MgO (1 0 0) surface were investigated using density functional theory. ...
Modified genetic algorithms to model cluster structures in medium-size silicon clusters
(American Physical Society, 2004)
Genetic algorithms (GA) were used to investigate the stable isomers of silicon clusters. In order to find the cluster structures, a semiempirical energy function was used by the GA that were further optimized using ...
Estudio de las propiedades electrónicas de cúmulos de Pd: un estudio comparativo usando distintas técnicas y aproximaciones
(SOC MEXICANA FISICA, 2008-04)
A systematic study of the colineal and no-colineal magnetic properties and the metallic behavior in free standing clusters of Pd-N (2 <= N <= 21) is carried out. We also study the effect of the twinning in clusters on the ...
Electronic and optical properties of [Au(CH3CSS)](4)cluster. A quantum chemistry study
(Royal Society of Chemistry, 2020)
The uses of the sulfur-gold bond in the design of new molecular clusters have gained increasing attention in recent years. Their size and shape are diverse providing a wide variety of optical and electronic properties. ...
