Propriedades estáticas e dinâmicas de portadores em heteroestruturas semicondutoras.
(Universidade Federal de São Carlos, 2002-10-30)
We have studied the dynamic and the stationary properties of carriers in semiconductor
heterostructures submitted to electric fields AC and DC and to magnetic fields
within the effective-mass approximation based on ...
Seções de choque diferenciais absolutas para o espalhamento elástico de elétrons de energias baixas e intermediárias por moléculas poliatômicas em fase gasosa
(Universidade Federal de São Carlos, 2002-05-27)
In this work we report absolute elastic differential cross sections (DCS) measurements for electron collisions with OCS, CO2, CH4, NO, N2O, CHF3 e C2F6 molecules in gas phase. The measurements cover the angular range from ...
Ansatz de Bethe para cadeias quânticas de spin-1 com condições de contorno
(Universidade Federal de São Carlos, 2002-03-21)
The procedure for obtaining integrable open spin chain Hamiltonians via reflection
matrices explicitly carried out for some three-state vertex models. We have considered
the 19-vertex models of Zamolodchikov-Fateev and ...
Ruídos e processos quânticos fundamentais em íons aprisionados e ondas propagantes
(Universidade Federal de São Carlos, 2002-07-22)
In this work we present a proposal protocol for engineering arbitrary motional states of trapped ions.Our scheme is based on both techniques of quantum state sculpture and projection synthesis. Next, we investigate the ...
