The Apparatus Strikes Back: Momentum Conservation and the Cost of Spatial Superpositions
Lucas C. Céleri, Diogo O. Soares-Pinto, Daniel A. Turolla Vanzella
The paper shows that momentum conservation forces any apparatus creating a spatial superposition of a massive particle to become entangled with the particle, and that the resulting…
Probing the limits of the semiclassical Einstein equation
Gustavo Schranck Habermann, Daniel A. Turolla Vanzella
In the context of semiclassical gravity, the semiclassical Einstein equation is often invoked when backreaction of quantum matter/fields on the spacetime is at stake. It is expecte…
Larmor radiation as a witness to the Unruh effect
Atsushi Higuchi, George E. A. Matsas, Daniel A. T. Vanzella +5
We discuss the emission of radiation from general sources in quantum scalar, electromagnetic and gravitational fields using the Rindler coordinate frame, which is suitable for a un…
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…
Globally hyperbolic evaporating black hole and the information loss issue
Juan V. O. Pêgas, André G. S. Landulfo, George E. A. Matsas +1
We discuss the information loss issue for completely evaporating black holes in the context of a globally hyperbolic spacetime that maintains unchanged the entire semiclassical pic…
The number of fundamental constants from a spacetime-based perspective
George E. A. Matsas, Vicente Pleitez, Alberto Saa +1
We revisit Duff, Okun, and Veneziano's divergent views on the number of fundamental constants and argue that the issue can be set to rest by having spacetime as the starting point.…
