摘      要：The Efimov scenario is a universal three-body effect addressing many areas of modern quantum *** plays an important role in the transition between few- and many-body physics and has enabled important breakthroughs in the understanding of the universal few-body *** review the basic concepts of the Efimov scenario with specific emphasis on the similarities and differences between homonuclear and heteronuclear *** the latter scenario,the existence of a second,independently tunable interaction parameter enables novel few-body phenomena that are universal and have no counterexamples in the homonuclear *** discuss recent experimental approaches using ultracold atomic gases with magnetically tunable interactions and elucidate the role of short-range interactions in the emergence of universal and non-universal behavior.
