The violation of the Hund rule in semiconductor artificial atoms
(2004)
The unrestricted Pople–Nesbet approach for real atoms is adapted to quantum dots under applied magnetic field. Gaussian basis sets are used instead of the exact single-particle orbitals in the construction of the appropriated ...
Restricted and unrestricted Hartree–Fock approaches applied to spherical quantum dots in a magnetic field
(2006)
The Roothaan and Pople–Nesbet approaches for real atoms are adapted to quantum dots in the presence of a magnetic field. Single-particle Gaussian basis sets are constructed, for each dot radius, under the condition of ...
Paleoenvironmental reconstruction using stable isotopes and trace elements from archaeological freshwater bivalve shell fragments in Northwest Patagonia, Argentina
(Pergamon-Elsevier Science Ltd, 2020-05)
Stable oxygen and carbon isotopes (18O and 13C) and the trace elements, manganese (Mn) and strontium (Sr) were analyzed in archaeological bivalve (Diplodon chilensis) shell fragments recovered from Parque Diana Cave, ...
Electronic properties of transition metal atoms on Cu2N/Cu(100)
(American Physical Society, 2015-11)
We study the nature of spin excitations of individual transition metal atoms (Ti, V, Cr, Mn, Fe, Co, and Ni) deposited on a Cu2N/Cu(100) surface using both spin-polarized density functional theory (DFT) and exact diagonalization ...

Problemática e perspectivas dos resíduos sólidos das conchas de mariscos originado da mariscagem nas comunidades tradicionais em Salinas da Margaria - Ba
(Universidade Federal da Bahia, Instituto de GeociênciasPrograma de pós-graduação em GeografiaUFBAbrasil, 2016-08-26)
RESUMO
Grande parte da concentração da população no Brasil se localiza no espaço
costeiro, por se mostrar desde o início da colonização do país, os locais mais
adequados para implantação de cidades, portos, plantações e ...

Exploitation of loco, Concholepas concholepas (Gastropoda: Muricidae), during the Holocene of Norte Semiárido, Chile
(Archaeopress Publishers of British Archaeological Reports Gordon House, 2008)
This paper is a contribution to the understanding of the possible causes leading to changes in size frequency, species distribution, and
abundance of Concholepas concholepas during the Holocene. We present a review of ...
