Dinâmica de sistemas bipartites de spins no espaço de fase quântico discreto
(Universidade Estadual Paulista (Unesp), 2010-02-22)
Quando temos sistemas quânticos sem análogo clássico a descrição de Weyl- Wigner, para o espaço de fase quântico, não pode ser utilizada, pois a mesma não representa graus de liberdade associados a grandezas discretas. Um ...
Role Of Multilevel Landau-zener Interference In Extreme Harmonic Generation

Ultrafast spin dynamics in II-VI diluted magnetic semiconductors with spin-orbit interaction
(American Physical Society, 2015-05)
We study theoretically the ultrafast spin dynamics of II-VI diluted magnetic semiconductors in the presence of spin-orbit interaction. Our goal is to explore the interplay or competition between the exchange sd coupling ...
Entanglement of excited states in critical spin chains
(IOP PUBLISHING LTDBRISTOL, 2012)
Renyi and von Neumann entropies quantifying the amount of entanglement in ground states of critical spin chains are known to satisfy a universal law which is given by the conformal field theory (CFT) describing their scaling ...
Decoerência de spin eletrônico em pontos quânticos

Classical evolution of quantum fluctuations in spin-like systems: Squeezing and entanglement
(2005)
It is shown that the quantum dynamics of spin coherent states governed by quadratic spin-like Hamiltonians, in the large spin limit, is well described in terms of evolution along classical trajectories on the two-dimensional ...
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 ...
Nonperturbative correlation effects in diluted magnetic semiconductors
(American Physical Society, 2016-01)
The effects of carrier-impurity correlations due to a Kondo-like spin-spin interaction in diluted magnetic semiconductors are investigated. These correlations are not only responsible for a transfer of spins between the ...
