We investigate the possible formation of a Bose-Einstein condensed phase of pions in the
early Universe at nonvanishing values of lepton flavor asymmetries. A hadron resonance …

The equation of state and phase diagram of strongly interacting matter composed of α
particles are studied in the mean-field approximation. The particle interactions are included …

Abstract We study the Bose–Einstein condensation in non-extensive statistics for a free gas
of bosons, and extend the results to the non-relativistic case as well. We present results for …

We study self-gravitating multipion systems (pion stars) in a state of Bose condensate. To
ensure stability of such stars, it is assumed that they are immersed in the lepton background …

The Bose-Einstein condensation and the liquid-gas first-order phase transition are studied in
the interacting pion matter. Two phenomenological models are used: The mean-field model …

Thermodynamics properties of an interacting system of bosons are considered at finite
temperatures and zero chemical potential within the Skyrme-like mean-field model. An …

Equation of state with quantum statistics corrections is derived for systems of the Fermi and
Bose particles by using their van der Waals (vdW) and effective density-dependent Skyrme …

Equation of state and electric (isospin) charge fluctuations are studied for matter composed
of interacting pions. The pion matter is described by self interacting scalar fields via a ϕ 4-ϕ …

A system of bosons studied within the mean-field framework has two fascinating
phenomena: a liquid-gas first order phase transition and Bose-Einstein condensation …

The interest in the Klein–Gordon equation with different potentials has increased in recent
years due to its possible applications in Cosmology, Hadron Physics and High-Energy …
