Saturation and Condensate Fraction Reduction of Cold Alpha Matter
The ground state energy of ideal α-matter at T = 0 is analyzed within the framework of variational theory of Bose quantum liquids. Calculations are done for three local α−α potentials with positive volume integrals and twobody correlation functions obtained from the Pandharipande-Bethe equation. The energy per particle of α matter is evaluated in the cluster expansion formalism up to four-body ...
متن کاملBose Condensate in External Potential : A Thomas - Fermi Approach
The Thomas-Fermi method [1] [2] was designed for the calculation of the electron density in a heavy atom, by treating the electrons as locally free. Lieb and Simon [3] showed that the treatment is exact in the limit when the atomic number goes to infinity. Application to a confined Bose condensate was pioneered by Goldman, Silvera, and Legget [4], and by Oliva [5], and recently reconsidered by ...
متن کاملCritical temperature and condensate fraction of a fermion pair condensate.
We report on measurements of the critical temperature and the temperature dependence of the condensate fraction for a fermion pair condensate of 6Li atoms. Bragg spectroscopy is employed to determine the critical temperature and the condensate fraction after a fast magnetic field ramp to the molecular side of the Feshbach resonance. Our measurements reveal evidence of level off of the critical ...
متن کاملHot Topics in Cold Gases
Since the first experimental realization of Bose-Einstein condensation in cold atomic gases in 1995 there has been a surge of activity in this field. Ingenious experiments have allowed us to probe matter close to zero temperature and reveal some of the fascinating effects quantum mechanics has bestowed on nature. It is a challenge for mathematical physicists to understand these various phenomen...
متن کاملUltra-cold Fermi gases
Molecule formation in ultracold degenerate quantum gases is one of the central topics in the overall ACQAO program, due to the strong quantum correlations in these systems. An experimental program in ultra-cold molecule formation using fermionic Li near a Feshbach resonance is underway at the SUT node of ACQAO. The work described here provides theoretical support for possible experimental inves...
