Semiclassical and quantum motions on the non-commutative plane
(ELSEVIER SCIENCE BV, 2009)
We study the canonical and the coherent state quantizations of a particle moving in a magnetic field on the non-commutative plane. Using a theta-modified action, we perform the canonical quantization and analyze the gauge ...
Supersymmetry in the non-commutative plane
(Academic Press Inc. Elsevier Science, 2005)
Dirac Oscillator in a Galilean Covariant Non-commutative Space
(International Journal of Theoretical Physics, 2013)
We study the Galilean Dirac oscillator in a non-commutative situation, with
space-space and momentum-momentum non-commutativity. The wave equation is obtained
via a ‘Galilean covariant’ approach, which consists in projecting ...
Existence of common zeros for commuting vector fields on 3-manifolds II. Solving global difficulties
(London Mathematics Society, 2020)
We address the following conjecture about the existence of common zeros for commuting vector fields in dimension 3: if are two commuting vector fields on a 3-manifold , and is a relatively compact open such that does not ...
Representações e aspectos quânticos de sistemas não-comutativos
(Universidade Federal de Minas GeraisUFMG, 2013-06-28)
This paper explores initially, in a intuitive form, some questions of non-commutativity in space well as the motivations for the study of non-commutative theories. Then be given an overight in some aspects of quantum theory ...
Boundaries in the Moyal plane
(Springer Heidelberg, 2013-12)
We study the oscillations of a scalar field on a noncommutative disc implementing the boundary as the limit case of an interaction with an appropriately chosen confining background. The space of quantum fluctuations of the ...
A note on noncommutative Chern–Simons model on manifolds with boundary
(World Scientific, 2002-01)
We study field theories defined in regions of the spatial noncommutative (NC) plane with a boundary present delimiting them, concentrating in particular on the U(1) NC Chern-Simons theory on the upper half-plane. We find ...
Modulação vetorial otimizada para o conversor packed U-cell
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2020-09-24)
This master’s dissertation proposes space vector modulation strategies for the Five-Levels Packed
U-Cell converter with optimization on the commutation number and balance of the floating
capacitors by use a cost function. ...
