Massive particle surfaces, partial umbilicity and circular orbits
Boris Bermúdez-Cárdenas, Oscar Lasso Andino
The generalization of photon spheres by considering the trajectories of massive particles leads to the definition of Massive Particle Surfaces (MPS). These surfaces are built with…
The Jacobi metric approach for dynamical wormholes
Álvaro Duenas-Vidal, Oscar Lasso Andino
We present the Jacobi metric formalism for dynamical wormholes. We show that in isotropic dynamical spacetimes , a first integral of the geodesic equations can be found using the J…
The quantum non-linear -model RG flow and integrability in wormhole geometries
Oscar Lasso Andino, Christian L. Vásconez
The target space of the non-linear -model is a Riemannian manifold. Although it can be any Riemannian metric, there are certain physically interesting geometries which are worth…
RG-2 flow, mass and entropy
Oscar Lasso Andino
The RG-2 flow is the two-loop approximation for the world-sheet non-linear sigma model renormalization group flow. The first truncation of the flow is the well known Ricci flow, at…
On gauged maximal d=8 supergravities
Oscar Lasso Andino, Tomas Ortin
We study the gauging of maximal supergravity using the embedding tensor formalism. We focus on SO gaugings, study all the possible choices of gauge fields and construct…
