Short Note on Spin Magnetization in QGP
Andrew Steinmetz, Johann Rafelski
We outline the theory of spin magnetization applicable to the QGP (quark-gluon plasma) epoch of the Universe. We show that a fully spin-polarized single flavor up-quark gas could g…

Quarks to Cosmos: Particles and Plasma in Cosmological evolution
Johann Rafelski, Jeremiah Birrell, Christopher Grayson +2
We describe in the context of the particle physics (PP) standard model (SM) `PP-SM' the understanding of the primordial properties and composition of the Universe in the temperatur…

Fermi-Dirac Integrals in Degenerate Regimes: A Novel Asymptotic Expansion
Jeremiah Birrell, Martin Formanek, Andrew Steinmetz +2
We characterize in a novel manner the physical properties of the low temperature Fermi gas in the degenerate domain as a function of temperature and chemical potential. For the fir…
