Gauge invariance and the CPT and Lorentz violating induced Chern-Simons-like term in extended QED
A. P. Baeta Scarpelli, Marcos Sampaio, M. C. Nemes +1
The radiative induction of the CPT and Lorentz violating Chern-Simons (CS) term is reassessed. The massless and massive models are studied. Special attention is given to the preser…
Extended Supersymmetric sigma-Model Based on the SO(2N+1) Lie Algebra of the Fermion Operators
Seiya Nishiyama, Joao da Providencia, Constanca Providencia +1
Extended supersymmetric sigma-model is given, standing on the SO(2N+1) Lie algebra of fermion operators composed of annihilation-creation operators and pair operators. Canonical tr…
The return of the membrane paradigm? Black holes and strings in the water tap
Vitor Cardoso, Oscar J. C. Dias, Leonardo Gualtieri
Several general arguments indicate that the event horizon behaves as a stretched membrane. We propose using this relation to understand gravity and dynamics of black objects in hig…
Orthogonality criterion for banishing hydrino states from standard quantum mechanics
Antonio S. de Castro
Orthogonality criterion is used to shown in a very simple and general way that anomalous bound-state solutions for the Coulomb potential (hydrino states) do not exist as bona fide…
