On regular charged black holes in three dimensions
Pablo Bueno, Oscar Lasso Andino, Javier Moreno +1
As argued in arXiv:2104.10172, introducing a non-minimally coupled scalar field, three-dimensional Einstein gravity can be extended by infinite families of theories which admit sim…
Massive particle surfaces and black hole shadows from intrinsic curvature
Boris Bermúdez-Cárdenas, Oscar Lasso Andino
In a recent article PRD 111, 064001 (2025) a new geometric a approach for studying massive particle surfaces was proposed. Using the Gaussian and geodesic curvatures of a two dimen…
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…
A Riemannian geometric approach for timelike and null spacetime geodesics
Marcos A. Argañaraz, Oscar Lasso Andino
The geodesic motion in a Lorentzian spacetime can be described by trajectories in a dimensional Riemannian metric. In this article we present a generalized Jacobi metric obtain…
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…
Dynamics in wormhole spacetimes: a Jacobi metric approach
Marcos Argañaraz, Oscar Lasso Andino
This article deals with the study of the dynamics of particles in different wormhole geometries. Using the Jacobi metric approach we study the geodesic motion on the Morris-Thorne…
