Propagating degrees of freedom on maximally-symmetric backgrounds in theories of gravity
Adrián Casado-Turrión, Álvaro de la Cruz-Dombriz, Antonio Dobado
In the context of gravity, as well as other extended theories of gravity, the correct counting of globally well-defined dynamical modes has recently drawn a vivid interest.…
Physical non-viability of a wide class of models and their constant-curvature solutions
Adrián Casado-Turrión, Álvaro de la Cruz-Dombriz, Antonio Dobado
Constant-curvature solutions lie at the very core of gravitational physics, with Schwarzschild and (Anti)-de Sitter being two of the most paradigmatic examples. Although such kind…
Is gravitational collapse possible in gravity?
Adrián Casado-Turrión, Álvaro de la Cruz-Dombriz, Antonio Dobado
Gravitational collapse is still poorly understood in the context of theories of gravity, since the Oppenheimer-Snyder model is incompatible with their junction conditions. I…
Brout-Englert-Higgs mechanism for accelerating observers
Antonio Dobado
In this work we consider the spontaneous symmetry breaking of the electroweak gauge group into taken place in the Standard Model of particle phys…
Spontaneous symmetry breaking and the Unruh effect
Antonio Dobado
In this work we consider the ontological status of the Unruh effect. Is it just a formal mathematical result? Or the temperature detected by an accelerating observer can lead to re…
The Raychaudhuri equation in homogeneous cosmologies
F. D. Albareti, J. A. R. Cembranos, A. de la Cruz-Dombriz +1
In this work we address the issue of studying the conditions required to guarantee the Focusing Theorem for both null and timelike geodesic congruences by using the Raychaudhuri eq…
