Van der Waals Plasma Universe During Reissner-Nordstrom Expansion

A two-component gas, consisting of ultra-relativistic ``normal'' particles with specific charge~$q$/$m$ and ``unusual'' particles with ultra-high charge $Q$ and ultra-high mass $M $described by a Reissner--Nordstr\"{o}m metric, is conceived as a van der Waals gas model of a plasma in early Universe. The model gives rise to an expansion process, Reissner-Nordstrom Expansion, that is analogues to a cosmic expansion during the radiation-dominated era. The Reissner-Nordstrom Expansion is due to the presence of a region with ``gravitational repulsion'' of the Reissner--Nordstr\"{o}m metric with respect to the ``normal'' particles with \textit{sign}($Q)q$/$m \ge -$1. The expansion era naturally ends at recombination. We discuss the equation of state of the two-component van der Waals gas and the range of model parameters within which the proposed expansion process is consistent with the restrictions regarding quantum effects.
