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…
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…
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…
