Generating Generalized solutions

N. Bretón, A. Feinstein, L. A. López +1

We show how one can systematically construct vacuum solutions to Einstein field equations with commuting Killing vectors in dimensions. The construction uses Einstein-s…

A universal Dirac operator and noncommutative spin bundles over fuzzy complex projective spaces

Brian P. Dolan, Idrish Huet, Sean Murray +1

We present a universal Dirac operator for noncommutative spin and spin^c bundles over fuzzy complex projective spaces. We give an explicit construction of these bundles, which are…

Crossing the phantom divide in an interacting generalized Chaplygin gas

H. Garcia-Compean, G. Garcia-Jimenez, O. Obregon +1

Unified generalized Chaplygin gas models assuming an interaction between dark energy and dark matter fluids have been previously proposed. Following these ideas, we consider a part…

Soliton Stability in a Generalized Sine-Gordon Potential

Ruben Cordero, Roberto D. Mota

We study stability of a generalized sine-Gordon model with two coupled scalar fields in two dimensions. Topological soliton solutions are found from the first-order equations that…

Deformation Quantization of Relativistic Particles in Electromagnetic Fields

Laura Sanchez, Imelda Galaviz, Hugo Garcia-Compean

The Weyl-Wigner-Moyal formalism for Dirac second class constrained systems has been proposed recently as the deformation quantization of Dirac bracket. In this paper, after a brief…
