About the quantum Talbot effect on the sphere
Fernando Chamizo, Osvaldo Santillan
The Schrödinger equation on a circle with an initially localized profile of the wave function is known to give rise to revivals or replications, where the probability density of th…
About apparent superluminal drives in generic gravity theories
J. Osorio Morales, O. Santillán
As is well known, there exists warp drives in GR, such as the Alcubierre bubbles, which achieve an apparent faster than light travel \cite{alcubierre}. A result due to Gao and Wald…
Electric and magnetic axion quark nuggets, their stability and their detection
O. Santillan, M. Sempe
The present work studies the dynamics of axion quark nuggets introduced in \cite{zhitnitsky} and exploited in the works \cite{zhitnitsky2}-\cite{zhitnitsky13}. The new feature cons…
Vacuum energy decay from a q-bubble
F. R. Klinkhamer, O. P. Santillan, G. E. Volovik +1
We consider a finite-size spherical bubble with a nonequilibrium value of the -field, where the bubble is immersed in an infinite vacuum with the constant equilibrium value $q_{…
About the Cauchy problem in Stelle's quadratic gravity
J. Osorio Morales, O. Santillán
The focus of the present work is on the Cauchy problem for the quadratic gravity models introduced in \cite{stelle}-\cite{stelle2}. These are renormalizable higher order derivative…
The existence of smooth solutions in q-theories
J. Osorio Morales, O. Santillan
The q-models are scenarios that may explain the smallness of the cosmological constant [1]-[7]. The vacuum in these theories is presented as a self-sustainable medium and include a…
