Aplicações de métodos perturbativos de TQC em modelos de baixa dimensionalidade e matéria condensada
(Universidade Federal de Minas GeraisUFMG, 2014-02-27)
Given the Implicit Regularization's success to separate and analyse spurious arbitrariness, which arise while treating divergent integrals, we proposed to apply this method in three distinct cases. In the rst, we compute ...

Point searching in real singular complete intersection varieties: Algorithms of intrinsic complexity
(American Mathematical Society, 2014-03)
Abstract. Let X1, . . .,Xn be indeterminates over Q and let X := (X1, . . . ,Xn). Let F1, . . . ,Fp be a regular sequence of polynomials in Q[X] of degreeat most d such that for each 1 ≤ k ≤ p the ideal (F1, . . . , Fk) ...
Spin filtering in all-electrical three-terminal interferometers
(American Physical Society, 2017-02-15)
Unlike the two-terminal device, in which the time-reversal invariant spin-orbit interaction alone cannot polarize the spins, such a polarization can be generated when electrons from one source reservoir flow into two (or ...
