The stress-energy tensor of an Unruh-DeWitt detector
T. Rick Perche, J. P. M. Pitelli, Daniel A. T. Vanzella
We propose a model for a finite-size particle detector, which allows us to derive its stress-energy tensor. This tensor is obtained from a covariant Lagrangian that describes not o…
Quantum Mechanics on Sharply Bent Wires via Two-Interval Sturm-Liouville Theory
João Paulo M. Pitelli, Ricardo A. Mosna, Felipe Felix Souto
We study quantum mechanics on a curved wire by approximating the physics around the curved region by three parameters coming from the boundary conditions given by the two interval…
Analogue model for anti-de Sitter as a description of point sources in fluids
Ricardo A. Mosna, J. P. M. Pitelli, Maurício Richartz
We introduce an analogue model for a nonglobally hyperbolic spacetime in terms of a two-dimensional fluid. This is done by considering the propagation of sound waves in a radial fl…
Scattering by a topological defect connecting two asymptotically Minkowski spacetimes
J. P. M. Pitelli, R. A. Mosna
We study the stability and the scattering properties of a spacetime with a topological defect along a spherical bubble. This bubble connects two flat spacetimes which are asymptoti…
