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 between these two phenomena is being investigated. Depending on the mean-field potential parameters one can observe two types of critical points, called ”Boltzmann” and ”Bose”, that belong to different universality classes with distinct sets of critical exponents. As examples of Bose and Boltzmann CPs pion and α matter are…

Bose-Einstein condensation and liquid-gas phase transition in alpha-matter

Systems of Bose particles with both repulsive and attractive interactions are studied using the Skyrme-like mean-field model. The phase diagram of such systems exhibits two special lines in the

Thermodynamic properties of interacting bosons with zero chemical potential

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 between attractive

Liquid-gas binodal anomaly for systems with pairing transition

Abstract:For fermionic model systems with a separable interaction the BCS equations are solved self-consistently. In addition, the possibility of a liquid-gas phase transition is considered by

The transition temperature of the dilute interacting Bose gas for N internal states

We calculate explicitly the variation δTc of the Bose-Einstein condensation temperature Tc induced by weak repulsive two-body interactions to leading order in the interaction strength. As shown

Quantum statistics effects near the critical point in systems with different interparticle interactions

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 mean-field

Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor

A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.

Mean-field approach in the multi-component gas of interacting particles applied to relativistic heavy-ion collisions

Generalized mean-field approach for thermodynamic description of relativistic single- and multi-component gas in the grand canonical ensemble is formulated. In the framework of the proposed approach

Bose–Einstein Condensate dark matter models in the presence of baryonic matter and random confining potentials

We consider the effects of an uncorrelated random potential on the properties of Bose–Einstein Condensate (BEC) dark matter halos, which acts as a source of disorder, and which is added as a new term
