Pion stars embedded in neutrino clouds
O. S. Stashko, O. V. Savchuk, L. M. Satarov +3
We study self-gravitating multi-pion systems (pion stars) in a state of the Bose condensate. To ensure stability of such stars, it is assumed that they are immersed in the lepton b…
Critical point influenced by Bose-Einstein condensation
V. A. Kuznietsov, O. Savchuk, O. S. Stashko +1
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. Interplay betwee…
Critical point and Bose-Einstein condensation in pion matter
V. A. Kuznietsov, O. S. Stashko, O. V. Savchuk +1
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 mode…
Phase diagram of interacting pion matter and isospin charge fluctuations
O. S. Stashko, O. V. Savchuk, R. V. Poberezhnyuk +2
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 vi…
Thermodynamic properties of interacting bosons with zero chemical potential
O. S. Stashko, D. V. Anchishkin, O. V. Savchuk +1
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 interplay…
Bose-Einstein condensation phenomenology in systems with repulsive interactions
Oleh Savchuk, Yehor Bondar, Oleksandr Stashko +4
The role of repulsive interactions in statistical systems of Bose particles is investigated. Three different phenomenological frameworks are considered: a mean field model, an excl…
