These properties can be strongly affected by axion dynamics in the early Universe, such as the axion string network and the non-linear dynamics around the QCD phase transition. Recently, improvements in numerical simulation techniques have allowed us to calculate the dark matter axion field from axion strings and QCD effects using different methods: directly with low-tension strings but high resolution [1], directly with effective high-tension strings [2], or indirectly by extrapolating an attractor solution [3]. In this work, we study the properties of miniclusters in the different approaches used in the literature. We find that, while there are substantial differences in the mass distribution and internal density profiles, globally there is a similar energy distribution between minicluster halos and voids. 000171743 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/PGC2022-126078NB-C21$$9info:eu-repo/grantAgreement/ES/MICINN/RYC2020-030244-I 000171743 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000171743 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000171743 700__ $$0(orcid)0000-0002-1044-8197$$aRedondo, Javier$$uUniversidad de Zaragoza 000171743 700__ $$aSaikawa, Ken'ichi 000171743 700__ $$aVaquero, Alejandro 000171743 700__ $$aMoore, Guy D. 000171743 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
