"Adaptive Mesh Refinement Simulations of Cosmological Scalar Fields"

Bodo Schwabe

(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.
