Aharonov-Bohm scattering for relativistic particles in (3 + 1)-dimensional noncommutative space with spin dependence
C. A. Stechhahn
We study the effects of noncommutativity of spacetime with mixed spatial and spin degrees of freedom in a relativistic context. Using the Dirac equation in (3+1) dimensions and in…
Dynamics of a Dirac Fermion in the presence of spin noncommutativity
A. F. Ferrari, M. Gomes, V. G. Kupriyanov +1
Recently, it has been proposed a spacetime noncommutativity that involves spin degrees of freedom, here called "spin noncommutativity". One of the motivations for such a constructi…
The 1/N Expansion in Noncommutative Quantum Mechanics
A. F. Ferrari, M. Gomes, C. A. Stechhahn
We study the 1/N expansion in noncommutative quantum mechanics for the anharmonic and Coulombian potentials. The expansion for the anharmonic oscillator presented good convergence…
Scattering of spin 1/2 particles by the 2+1 dimensional noncommutative Aharonov-Bohm potential
A. F. Ferrari, M. Gomes, C. A. Stechhahn
In this work we study modifications in the Aharonov-Bohm effect for relativistic spin 1/2 particles due to the noncommutativity of spacetime in dimensions. The noncommutati…
