Partial Secrecy Analysis in Wireless Systems: Diversity-Enhanced PLS over Generalized Fading Channels
Henry Carvajal Mora, Nathaly Orozco, Fernando Almeida García +3
Securing information in future mobile networks is challenging, especially for devices with limited computational resources. Physical layer security (PLS) offers a viable solution b…
Finite time blow-up for a nonlinear parabolic equation with smooth coefficients
Oscar Jarrin, Gaston Vergara-Hermosilla
In this article, we consider an n-dimensional parabolic partial differential equation with a smooth coefficient term in the nonlinear gradient term. This equation was first introdu…
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…
An Lp-theory for fractional stationary Navier-Stokes equations
Oscar Jarrín, Gastón Vergara-Hermosilla
We consider the stationary (time-independent) Navier-Stokes equations in the whole threedimensional space, under the action of a source term and with the fractional Laplacian opera…
Conformal bounds in three dimensions from entanglement entropy
Pablo Bueno, Horacio Casini, Oscar Lasso Andino +1
The entanglement entropy of an arbitrary spacetime region in a three-dimensional conformal field theory (CFT) contains a constant universal coefficient, . For general the…
A turbulent study for a damped Navier-Stokes equation: turbulence and problems
Diego Chamorro, Oscar Jarrín
In this article we consider a damped version of the incompressible Navier-Stokes equations in the whole three-dimensional space with a divergence-free and time-independent external…
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…
Some remarks on the regularity of weak solutions for the stationary Ericksen-Leslie and MHD systems
Oscar Jarrín
We consider two elliptic coupled systems of relevance in the fluid dynamics. These systems are posed on the whole three-dimensional space and they consider the action of external f…
Aspects of N-partite information in conformal field theories
César A. Agón, Pablo Bueno, Oscar Lasso Andino +1
We present several new results for the -partite information, , of spatial regions in the ground state of -dimensional conformal field theories. First, we show that …
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…
Disks globally maximize the entanglement entropy in dimensions
Pablo Bueno, Horacio Casini, Oscar Lasso Andino +1
The entanglement entropy corresponding to a smooth region in general three-dimensional CFTs contains a constant universal term, . For a disk region, $F|_{…
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…
RG-2 flow and black hole entanglement entropy
Oscar Lasso Andino
We study the evolution of a metric of a two dimensional black hole under the second loop renormalization group fow, the RG-2 fow. Since the black hole metric is noncompact (we cons…
