12 Jan 2007 | | Subject: | Statistical Mechanics; Other | | Abstract: | We propose a new form of the inversion method in terms of a selfenergy expansion to access the phase diagram of the Bose-Einstein transition. The dependence of the critical temperature on the interaction parameter is calculated. This is discussed with the help of a new condition for Bose-Einstein condensation in interacting systems which follows from the pole of the T-matrix in the same way as from the divergence of the medium-dependent scattering length. A many-body approximation consisting of screened ladder diagrams is proposed which describes the Monte Carlo data more appropriately. The specific results are that a non-selfconsistent T-matrix leads to a linear coefficient in leading order of 4.7, the selfconsistent T-matrix due to the effective mass to a coefficient of 1.3 and the screened ladder approximation to 2.3 close to the Monte Carlo data. | | Source: | arXiv, cond-mat/0701280 | | Services: | Forum | Review | PDF | Favorites | |
