Universal -matrices for quantum Poincaré groups: contractions and quantum reference frames
Angel Ballesteros, Diego Fernandez-Silvestre, Ivan Gutierrez-Sagredo
Universal -matrices, or Hopf algebra dual forms, for quantum groups are revisited, and their contraction theory is developed. As a first illustrative example, the (1+1) timelike…
Quantum Galilei group as quantum reference frame transformations
Angel Ballesteros, Diego Fernandez-Silvestre, Flaminia Giacomini +1
Quantum groups have been widely explored as a tool to encode possible nontrivial generalisations of reference frame transformations, relevant in quantum gravity. In quantum informa…
Physical reinterpretation of heat capacity discontinuities for static black holes
Pedro Bargueño, Diego Fernández-Silvestre, Juan A. Miralles
A generic characteristic of self-gravitating systems is that they have a negative heat capacity. An important example of this behavior is given by the Schwarzschild black hole. The…
Upon the horizon's verge: Thermal particle creation between and approaching horizons
Diego Fernández-Silvestre, Michael R. R. Good, Eric V. Linder
Quantum particle creation from spacetime horizons, or accelerating boundaries in the dynamical Casimir effect, can have an equilibrium, or thermal, distribution. Using an accelerat…
On the duality of Schwarzschild-de Sitter spacetime and moving mirror
Diego Fernández-Silvestre, Joshua Foo, Michael R. R. Good
The Schwarzschild-de Sitter (SdS) metric is the simplest spacetime solution in general relativity with both a black hole event horizon and a cosmological event horizon. Since the S…
