The BCS-BEC Crossover

Research output: Chapter in Book/Report/Conference proceedingChapter (Book)Researchpeer-review


This chapter presents the crossover from the Bardeen–Cooper–Schrieffer (BCS) state of weakly correlated pairs of fermions to the Bose–Einstein condensation (BEC) of diatomic molecules in the atomic Fermi gas. Our aim is to provide a pedagogical review of the BCS–BEC crossover, with an emphasis on the basic concepts, particularly those that are not generally known or are difficult to find in the literature. We shall not attempt to give an exhaustive survey of current research in the limited space here; where possible, we will direct the reader to more extensive reviews.
