QCD spin physics: Partonic spin structure of the nucleon
(Elsevier Science, 2012-04)
We discuss some recent developments concerning the nucleon's helicity parton distribution functions: new preliminary data from jet production at RHIC suggest for the first time a non-vanishing polarization of gluons in the ...
Estudo experimental de efeitos de spin em heteroestruturas semicondutoras
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2015-04-28)
In this thesis, we have investigated optical and spin properties of semiconductor
nanostructures. Photoluminescence and magneto-photoluminescence measurements
were performed in high magnetic field (B ≤ 15T), in GaBiAs ...
Origin of spin incommensurability in hole-doped S=1 Y2-xCaxBaNiO5 chains
(American Physical Soc, 2001-04-01)
Spin incommensurability (IC) has been recently experimentally discovered in the hole-doped Ni-oxide chain compound Y2-xCaxBaNiO5 [G. Xu et al., Science 289, 419 (2000)]. Here a two orbital model for this material is studied ...
Towards coherent optical control of a single hole spin: Rabi rotation of a trion conditional on the spin state of the hole
(Pergamon-Elsevier B.V. Ltd, 2014)
Relation between halo spin and cosmic-web filaments at z similar or equal to 3
(2017)
We investigate the spin evolution of dark matter haloes and their dependence on the number of connected filaments from the cosmic web at high redshift (spin-filament relation hereafter). To this purpose, we have simulated ...
Um modelo de excitações interagentes para descrição de gelos de spins artificiais
(Universidade Federal de Minas GeraisUFMG, 2018-05-04)
Artificial spin ice is a class of two dimensional nanomagnetic systems fabricated by litography. They are initially proposed to resemble the crystalline spin ice, allowing the theoretical and experimental investigation of ...
