Born-Oppenheimer Type Approximation for a Simple Renormalizable System,hough intuitively clear the actual application of the Born-Oppenheimer type approximation to this problem is quite subtle.

Thermodynamic Properties of Ultracold Fermi Gases Across the BCS-BEC Crossover and the Bertsch ProbIn this chapter we review the thermodynamic properties of ultracold Fermi gases in which the strength of the interaction is continuously varied. The system features a crossover between a state described by the BCS theory of superconductivity and a Bose-Einstein condensate. A discussion of the Bertsch problem is presented.作者: 禁令 時間: 2025-3-26 21:46
