Dispersion Relations in Noncommutative Theories
Tiago Mariz, J. R. Nascimento, Victor O. Rivelles
We present a detailed study of plane waves in noncommutative abelian gauge theories. The dispersion relation is deformed from its usual form whenever a constant background electrom…
The Noncommutative Anandan's Quantum Phase
E. Passos, L. R. Ribeiro, C. Furtado +1
In this work we study the noncommutative nonrelativistic quantum dynamics of a neutral particle, that possesses permanent magnetic and electric dipole momenta, in the presence of a…
Remarks on Lorentz and CPT violation in field theory
T. Mariz, J. R. Nascimento, E. Passos
In this brief review we explicitly calculate the radiative corrections to the Chern-Simons-like term in the cases of zero and finite temperature, and in the gravity theory. Our res…
Lorentz violation in the linearized gravity
A. F. Ferrari, M. Gomes, J. R. Nascimento +3
We study some physical consequences of the introduction of a Lorentz-violating modification term in the linearized gravity, which leads to modified dispersion relations for gravita…
The three-dimensional non-anticommutative superspace
A. F. Ferrari, M. Gomes, J. R. Nascimento +2
We propose two alternative formulations for a three-dimensional non-anticommutative superspace in which some of the fermionic coordinates obey Clifford anticommutation relations. F…
The Effective Potential in the Noncommutative Field Theories within the Coherent States Approach
M. A. Anacleto, J. R. Nascimento, A. Yu. Petrov
We apply the coherent state approach to study the noncommutative scalar field theory with self-interaction and Yukawa coupling to the spinor field. We verify that, contrarily…
