Abstract

Recent developments of quantum systems called ultracold Fermi atomic gases have experimentally revealed a continuous crossover from the Bardeen-Cooper-Schrieffer (BCS) superfluidity, accompanied by Cooper pair formation, to the Bose-Einstein condensates (BEC) of tightly bound molecules, by changing the two-particle inter-atomic interactions associated with the Feshbach resonance. In this talk, we discuss the similarity between this many-body phenomenon, known as the BCS-BEC crossover, and the hadron-quark crossover expected to occur in neutron star interiors.
