Granular Structure and Local de Broglie Wavelength in Fuzzy Dark Matter Halos
Flavio Rosales-Infante, Alejandro Quiñonez-Guerrero, Iván Álvarez-Rios +1
We study the granular structure that emerges in a Fuzzy Dark Matter (FDM) halo formed through kinetic relaxation. After the system reaches a virialized core-halo structure, we sepa…
Schwarzschild black holes as low-pass filters of fuzzy dark matter granularity
Flavio Rosales-Infante, Iván Álvarez-Rios, Francisco S. Guzmán
We study the relaxation of a complex massive scalar field around a supermassive black hole, modeling the near-horizon dynamics of Fuzzy Dark Matter (FDM) with spatial granularity.…
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…
Temporal Correlations Between Fuzzy Dark Matter and Baryonic Matter in Virialized Core-Halo Structures
Ivan Alvarez-Rios, Francisco S. Guzman
Fuzzy Dark Matter (FDM) predicts the existence of virialized halos with interference-driven granular structure generated by the wave nature of ultralight bosons. Since these fluctu…
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…
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…
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…
Spherical solutions of the Schrödinger-Poisson system with core-tail structure
Iván Álvarez-Rios, Francisco S. Guzmán
We construct spherically symmetric equilibrium solutions of the Schrödinger-Poisson (SP) system of equations with a core-tail structure that could serve as models of Fuzzy Dark Mat…
The Effect of Boundary Conditions on Structure Formation in Fuzzy Dark Matter
Iván Alvarez-Ríos, Francisco S. Guzmán, Paul R. Shapiro
We illustrate the effect of boundary conditions on the evolution of structure in Fuzzy Dark Matter. Scenarios explored include the evolution of single, ground-state equilibrium sol…
Stationary solutions of the Schrödinger-Poisson-Euler system and their stability
Iván Álvarez-Rios, Francisco S. Guzmán
We present the construction of stationary boson-fermion spherically symmetric configurations governed by Newtonian gravity. Bosons are described in the Gross-Pitaevskii regime and…
Exploration of simple scenarios involving Fuzzy Dark Matter cores and gas at local scales
Iván Alvarez-Ríos, Francisco S. Guzmán
We introduce a tool that solves the Schrödinger-Euler-Poisson system of equations and allows the study of the interaction between ultralight bosonic dark matter, whose dynamics is…
