Photon Scattering by an Electric Field in Noncommutative Spacetime
Daniela D'Ascanio, Pablo Pisani, Ulises Wainstein Haimovichi
As is known, the existence of a small noncommutativity between coordinates would generate nonlocal self-interactions in the electromagnetic theory. To explore some consequences of…
Affine Killing vector fields on homogeneous surfaces with torsion
Daniela D'Ascanio, Peter Gilkey, Pablo Pisani
Many extensions of General Relativity are based on considering metric and affine structures as independent properties of spacetime. This leads to the possibility of introducing tor…
Renormalization on noncommutative torus
D. D'Ascanio, P. Pisani, D. V. Vassilevich
We study a self-interacting scalar theory on the -dimensional noncommutative torus. We determine, for the particular cases and , the counterterms required by on…
On the algebraic structure of rotationally invariant two-dimensional Hamiltonians on the noncommutative phase space
H. Falomir, P. A. G. Pisani, F. Vega +3
We study two-dimensional Hamiltonians in phase space with noncommutativity both in coordinates and momenta. We consider the generator of rotations on the noncommutative plane and t…
Boundaries in the Moyal plane
H. Falomir, S. A. Franchino Viñas, P. A. G. Pisani +1
We study the oscillations of a scalar field on a noncommutative disc implementing the boundary as the limit case of an interaction with an appropriately chosen confining background…
Magnetic-Dipole Spin Effects in Noncommutative Quantum Mechanics
H. Falomir, J. Gamboa, J. Lopez-Sarrion +2
A general three-dimensional noncommutative quantum mechanical system mixing spatial and spin degrees of freedom is proposed. The analogous of the harmonic oscillator in this descri…
Self-adjoint extensions and SUSY breaking in Supersymmetric Quantum Mechanics
H. Falomir, P. A. G. Pisani
We consider the self-adjoint extensions (SAE) of the symmetric supercharges and Hamiltonian for a model of SUSY Quantum Mechanics in with a singular superpotential.…
Algebraic Solution of the Supersymmetric Hydrogen Atom in d Dimensions
A. Kirchberg, J. D. Laenge, P. A. G. Pisani +1
In this paper the N=2 supersymmetric extension of the Schroedinger Hamiltonian with 1/r-potential in arbitrary space-dimensions is constructed. The supersymmetric hydrogen atom adm…
