摘要: Studies of superfluidity in ultracold trapped Fermi gases are attracting physicists from a wide range sub-disciplines including nuclear, condensed matter and particle physics. The excitement the field is due, large part, to remarkable tuneability these gases. One can tune attractive interaction strength continuously weak strong (thereby effecting transition BCS Bose Einstein (BEC) superfluid). introduce polarization into at will, which may lead long-sought-after, but not yet confirmed, exotic superfluid phases. In this talk we discuss relevance cold other physics subdisciplines. We then summarize how BCS-BEC crossover connects with particularly important topic matter: high temperature superconductivity. emphasize some striking similarities relating very unusual normal or 'pseudogap' phase each two systems. process give summary latest exciting experimental developments fields.
