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…
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…
Construction of ground state solutions of the Gross-Pitaevskii-Poisson system using genetic algorithms
Carlos Tena-Contreras, Ivan Alvarez-Rios, F. S. Guzman
We present the construction of the ground state of the Gross-Pitaevskii-Poisson equations using genetic algorithms. By employing numerical solutions, we develop an empirical formul…
Unveiling Orbital Chaos: The Wild Heart of Fuzzy Dark Matter Structures
Ivan Alvarez-Rios, Francisco S. Guzman
In this paper we study the behavior of test particles on top of a galactic-type of Fuzzy Dark Matter (FDM) structure, characterized by the core-halo density profile found in simula…
Numerical Solution Partial Differential Equations using the Discrete Fourier Transform
Daniela Rodriguez-Lara, Ivan Alvarez-Rios, Francisco S. Guzman
In this paper we explain how to use the Fast Fourier Transform (FFT) to solve partial differential equations (PDEs). We start by defining appropriate discrete domains in coordinate…
Black Holes as Condensation Points of Fuzzy Dark Matter Cores
Curicaveri Palomares-Chavez, Ivan Alvarez-Rios, Francisco S. Guzman
We simulate the formation of Fuzzy Dark Matter (FDM) cores in the presence of a Black Hole (BH) to explore whether BHs can serve as seeds for FDM core condensation. Our analysis is…
Fermion-Boson Stars as Attractors in Fuzzy Dark Matter and Ideal Gas Dynamics
Ivan Alvarez-Rios, Francisco S. Guzman, Jens Niemeyer
In the context of Fuzzy Dark Matter (FDM) we study the core formation in the presence of an Ideal Gas (IG). Our analysis is based on the solution of the Schrödinger-Poisson-Euler s…
Galactic Rotation Curves of LSB Galaxies using core-halo FDM configurations
Ivan Alvarez-Rios, Tula Bernal, Pierre-Henri Chavanis +1
In this work, we construct galactic halos in order to fit the rotation curves (RCs) of a sample of low surface brightness (LSB) galaxies. These halos are made of Fuzzy Dark Matter…
Variational Quantum Crank-Nicolson and Method of Lines for the Solution of Initial Value Problems
Francisco Guzman-Cajica, Francisco S. Guzman
In this paper we use a Variational Quantum Algorithm to solve Initial Value Problems with the Implicit Crank-Nicolson and the Method of Lines (MoL) evolution schemes. The unknown f…
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…
Merger of galactic cores made of ultralight bosonic dark matter
