Conic Constrained Particle Quantization within the DB, FJBW and BRST Approaches
Gabriel D. Barbosa, Ronaldo Thibes
We consider a second degree algebraic curve describing a general conic constraint imposed on the motion of a massive spinless particle. The problem is trivial at classical level bu…
Noncommutative Conformally Coupled Scalar Field Cosmology and its Commutative Counterpart
G. D. Barbosa
We study the implications of a noncommutative geometry of the minisuperspace variables for the FRW universe with a conformally coupled scalar field. The investigation is carried ou…
Noncommutative Geometry and Cosmology
G. D. Barbosa, N. Pinto-Neto
We study some consequences of noncommutativity to homogeneous cosmologies by introducing a deformation of the commutation relation between the minisuperspace variables. The investi…
Noncommutative quantum mechanics and Bohm's ontological interpretation
G. D. Barbosa, N. Pinto-Neto
We carry out an investigation into the possibility of developing a Bohmian interpretation based on the continuous motion of point particles for noncommutative quantum mechanics. Th…
On the Meaning of the String-Inspired Noncommutativity and its Implications
G. Dourado Barbosa
We propose an alternative interpretation for the meaning of noncommutativity of the string-inspired field theories and quantum mechanics. Arguments are presented to show that the n…
