Accretion of multipolar massive complex scalar field packets by a Schwarzschild black hole

Flavio Rosales-Infante, Ivan Alvarez-Rios, Francisco S. Guzman

We study the finite-time accretion of complex massive scalar wave packets by a Schwarzschild black hole in the test-field regime, with parameters motivated by ultralight fuzzy dark…

Equilibrium Core and Vortex Solutions of Bose Einstein Condensate Dark Matter around a Black Hole

Ivan Alvarez-Rios, Francisco S. Guzman

We present the construction of stationary solutions of Bose-Einstein condensate dark matter (BECDM) around a point-like gravitational source representing a black hole. The problem…

Time-dependent adaptive mesh refinement solver for the Gross-Pitaevskii-Poisson equations

Iván Álvarez-Rios

This work presents a new numerical code for solving the time--dependent Gross--Pitaevskii--Poisson (GPP) system using adaptive mesh refinement (AMR). The code is designed to study…

Kinematic Imprints of vortex-lines of BEC Dark Matter on Baryonic Matter

Iván Álvarez-Rios, Carlos Tena-Contreras, Francisco S. Guzmán

Our results demonstrate that vortex lines in Bose-Einstein Condensate Dark Matter (BECDM) can act as gravitational seeds that induce the condensation of baryonic matter, leading to…

Plain Convolution Encryption as an Alternative to Overcoming the Limitations of Synchronization-Based Methods

Flavio Rosales-Infante, M. L. Romero-Amezcua, Iván Álvarez-Rios +1

This paper revisits the send/retrieve message process using synchronization of the Lorenz system with a monochromatic message. We analyze how the fidelity of the retrieved signal d…
