Effect of Interactions on the Critical Temperature of a Dilute Bose Gas
نویسنده
چکیده
Due to the observation of Bose-Einstein condensation in dilute atomic 87Rb and 23Na vapors last year, there is currently a great interest in the properties of a degenerate Bose gas. One aspect that is not yet understood is the effect of the interatomic interactions on the critical temperature of the phase transition. We present here a renormalization group study of the weakly-interacting Bose gas and predict the critical temperature at which Bose-Einstein condensation occurs as a function of the (positive) scattering length a of the interatomic potential.

Estimation of Binary Infinite Dilute Diffusion Coefficient Using Artificial Neural Network
In this study, the use of the three-layer feed forward neural network has been investigated for estimating of infinite dilute diffusion coefficient ( D12 ) of supercritical fluid (SCF), liquid and gas binary systems. Infinite dilute diffusion coefficient was spotted as a function of critical temperature, critical pressure, critical volume, normal boiling point, molecular volume in normal boilin...
متن کاملCritical Temperature of a Trapped Interacting Bose Gas in the Local Density Approximation
The Bose gas in an external potential is studied by means of the local density approximation. An analytical result is derived for the dependence of the critical temperature of Bose-Einstein condensation on the mutual interaction in a generic power-law potential. PACS numbers: 03.75.Fi, 32.80.Pj In an ideal Bose-Einstein gas, the zero momentum state can become macroscopically occupied, and the s...
متن کاملCritical temperature of Bose–Einstein condensation in trapped atomic Bose–Fermi mixtures
We calculate the shift in the critical temperature of Bose-Einstein condensation for a dilute Bose-Fermi mixture confined by a harmonic potential to lowest order in both the Bose-Bose and Bose-Fermi coupling constants. The relative importance of the effect on the critical temperature of the boson-boson and boson-fermion interactions is investigated as a function of the parameters of the mixture...
متن کاملMulticritical crossovers near the dilute bose gas quantum critical point.
Many zero temperature transitions, involving the deviation in the value of a U(1) conserved charge from a quantized value, are described by the dilute Bose gas quantum critical point. On such transitions, we study the consequences of perturbations which break the symmetry down to ZN in d spatial dimensions. For the case d = 1, N = 2, we obtain exact, finite temperature, multicritical crossover ...
متن کامل0 T c for dilute Bose gases : beyond leading order in 1 / N
Second-order phase transitions have universal behavior, associated with long wavelength fluctuations, for which critical exponents and other universal quantities can often be successfully calculated using renormalization group techniques. For most such systems, the short distance physics is hopelessly complicated. In contrast, the phase transition of a dilute, interacting Bose gas provides a fa...
