"Adaptive Mesh Refinement Simulations of Cosmological Scalar Fields"
(Departamento de Física Teórica)
Over the past 15 months that I have had the please to be part
of the Departamento de Física Teórica I continued my broad research
on adaptive mesh refinement (AMR) simulations of cosmological scalar
fields. In this seminar talk I will highlight the main scientific
results that are the product of my stay at the Universidad de Zaragoza.
This includes a new numerical method for ultra-deep zoom-in simulations
of cosmological structure formation with fuzzy dark matter allowing
numerical analyses of Milky Way-sized halos. Additionally, I will
present preliminary results of cosmological structure formation
suppression in scenarios where fuzzy dark matter is considered as an
admixture to cold dark matter. The same numerical techniques are
utilized for gravitational collapse simulations of the inflaton field in
the post-inflationary, matter dominated Universe. Finally, I will
highlight numerical results of QCD axion evolution assuming PQ-symmetry
breaking after inflation using AMR techniques to better resolve axion
strings and axitons for increasingly realistic simulations.
