Decoherencia en el transporte cuántico : descripciones dinámicas y procesos dependientes de espín
(2016-03)
La pérdida de correlación de fase en un sistema cuántico es conocida como decoherencia y es consecuencia de las interacción con el ambiente.
En esta tesis nos enfocamos en desarrollar herramientas teóricas y numéricas que ...
Transporte de portadores minoritários que justificam o regime de ressonância eletrônica em sistemas de carbynes
(Universidade Federal do ParáBrasilPós-Graduação em Engenharia ElétricaBelém, 2017)
Sistema para controle de frotas do transporte coletivo com acessibilidade para deficientes visuais
(Universidade Tecnológica Federal do ParanáPato Branco, 2014-02-20)
Transit riders who have a visual impairment , often encounter difficulties in the simple task of getting around the city where he lives , often depending on the help of strangers or a companion . Seeking to improve this ...
Electrochemical insight into the mechanism of electron transport in biofilms of Geobacter sulfurreducens
(Elsevier, 2011-07-08)
Electroactive bacterial biofilms can be produced on a polarized electrode by forcing its use as the final electron acceptor for bacterial respiration. This strategy offers the researcher the unique possibility to control ...
Nonlinear transport in n-III-nitrides: Selective amplification and emission of coherent LO phonons
(Pergamon-elsevier Science LtdOxfordInglaterra, 2006)
Efectos de la radiación en las propiedades eléctricas del grafeno : estados topológicos de Floquet inducidos por láser
(2015-12)
Esta tesis está dedicada al estudio teórico del grafeno iluminado por un láser intenso. Nos enfocamos en efectos no perturbativos de la luz sobre el material, utilizando la teoría de Floquet. Mostramos cómo un láser puede ...
Numerical study of the spherically symmetric Gross-Pitaevskii equation in two space dimensions
(2000-08-01)
The Gross-Pitaevskii equation for Bose-Einstein condensation (BEC) in two space dimensions under the action of a harmonic oscillator trap potential for bosonic atoms with attractive and repulsive interparticle interactions ...
EINSTEIN RELATION FOR NONLINEAR CHARGE-TRANSPORT IN PHOTOEXCITED POLAR SEMICONDUCTORS
(Pergamon-elsevier Science LtdOxfordInglaterra, 1994)
Nonequilibrium transport through magnetic vibrating molecules
(American Physical Society, 2013-05)
We calculate the nonequilibrium conductance through a molecule or a quantum dot in which the occupation of the relevant electronic level is coupled with intensity λ to a phonon mode and also to two conducting leads. The ...
Effects of hydroxamic acids on electron transport and their cellular location in corn
(1994)
DIMBOA, the main hydroxamic acid in maize and wheat, is found mainly as a glucoside in intact maize plants; when the tissue is damaged a β-glucosidase releases DIMBOA from DIMBOA-glucoside. The effects of DIMBOA and its ...
