Stability of the spacetime of a magnetized compact object
Eveling C. Ribeiro, L. Formigari, Marcos R. Ribeiro +5
We investigate the stability of scalar perturbations around a magnetized stationary compact object in General Relativity. The considered object is one of the simplest exact solutio…
Entanglement in a Maxwell Theory coupled to a non-relativistic particle
Filiberto Ares, Amilcar R. de Queiroz, Marcia R. Tenser
We consider electromagnetism in a cylindrical manifold coupled to a nonrelativistic charged point-particle. Through the relation between this theory and the Landau model on a torus…
Near-horizon modes and self-adjoint extensions of the Schroedinger operator
A. P. Balachandran, A. R. de Queiroz, Alberto Saa
We investigate the dynamics of scalar fields in the near-horizon exterior region of a Schwarzschild black hole. We show that low-energy modes are typically long-living and might be…
Novel Edge States in Self-Dual Gravity
A. P. Balachandran, Amilcar R. de Quieroz, M. Arshad Momen
In contrast to the Einstein-Hilbert action, the action for self-dual gravity contains vierbeins. They are eleminated at the level of observables by an gauge cond…
Entanglement and Particle Identity: A Unifying Approach
A. P. Balachandran, T. R. Govindarajan, Amilcar R. de Queiroz +1
It has been known for some years that entanglement entropy obtained from partial trace does not provide the correct entanglement measure when applied to systems of identical partic…
