Horava-Lifshitz modifications of the Casimir effect
A. F. Ferrari, H. O. Girotti, M. Gomes +2
We study the modifications induced by spacetime anisotropy on the Casimir effect in the case of two parallel plates. Nonperturbative and perturbative regimes are analyzed. In the f…
Noncommutative quantum mechanics as a gauge theory
F. S. Bemfica, H. O. Girotti
The classical counterpart of noncommutative quantum mechanics is a constrained system containing only second class constraints. The embedding procedure formulated by Batalin, Fradk…
Noncommutative quantum mechanics: uniqueness of the functional description
F. S. Bemfica, H. O. Girotti
The generalized Weyl transform of index is used to implement the time-slice definition of the phase space path integral yielding the Feynman kernel in the case of noncommutativ…
Born series and unitarity in noncommutative quantum mechanics
F. S. Bemfica, H. O. Girotti
This paper is dedicated to present model independent results for noncommutative quantum mechanics. We determine sufficient conditions for the convergence of the Born series and, in…
Lorentz symmetry breaking in the noncommutative Wess-Zumino model: One loop corrections
A. F. Ferrari, H. O. Girotti, M. Gomes
In this paper we deal with the issue of Lorentz symmetry breaking in quantum field theories formulated in a non-commutative space-time. We show that, unlike in some recente analysi…
The noncommutative degenerate electron gas
F. S. Bemfica, H. O. Girotti
The quantum dynamics of nonrelativistic single particle systems involving noncommutative coordinates, usually referred to as noncommutative quantum mechanics, has lately been the o…
