چکیده
We calculate the ultra-relativistic Bose-Einstein condensation temperature of a complex scalar field with weak λ(Φ†Φ)2 interaction. We show that at high temperature and finite density we can use dimensional reduction to produce an effective three-dimensional theory which then requires non-perturbative analysis. For simplicity and ease of implementation we illustrate this process with the linear delta expansion.

The Effect of Weak Interactions on the Ultra-Relativistic Bose-Einstein Condensation Temperature
We calculate the ultra-relativistic Bose-Einstein condensation temperature of a complex scalar field with weak λ(Φ†Φ)2 interaction. To do this we dimensionally reduce the theory, then perform a non-perturbative analysis on the resulting effective three-dimensional theory. For simplicity and ease of implementation we use the linear delta expansion.

We study the Bose-Einstein condensation (BEC) for a relativistic ideal gas of bosons. In the framework of canonical thermal field theory, we analyze the role of particles and anti-particles in the determination of BEC transition temperature. At the BEC transition point we obtain two universal curves, i.e. valid for any mass value: the scaled critical temperature as a function of the scaled char...

This article reviews recent investigations on the phenomenon of Bose-Einstein condensation of dilute gases. Since the experimental observation of quantum degeneracy in atomic gases, the research activity in the field of coherent matter-waves literally exploded. The present topical review aims to give an introduction into the thermodynamics of Bose-Einstein condensation, a general overview over ...
متن کاملSimple criterion for the occurrence of Bose-Einstein condensation and the Meissner-Ochsenfeld effect
We examine the occurrence of Bose-Einstein condensation in both nonrelativistic and relativistic systems with no self-interactions in a general setting. A simple condition for the occurrence of Bose-Einstein condensation is given. We show that condensation can occur only if q ≥ 3, where q is the dimension associated with the continuous part of the eigenvalue spectrum of the Hamiltonian for nonr...

We discuss the Bose-Einstein condensation (BEC) for an ideal gas of bosons in the framework of Tsallis's nonextensive statistical mechanics. We study the corrections to the standard BEC formulas due to a weak nonextensivity of the system. In particular, we consider three cases in the D-dimensional space: the homogeneous gas, the gas in a harmonic trap and the relativistic homogenous gas. The re...
