Abstract
Ultracold atomic gases have provided deep insight intoquantum many-body systems, since the realization of aquantum degenerate gas, such as a Bose-Einstein con-densate (BEC) [1] and a degenerate Fermi gas [2]. Oneof the intriguing new developments in this field is a studyof quantum degeneracy in a mixed gas. An advantage inthe study using ultracold atomic mixed gases is the abil-ity to select the statistics of atomic gases: a Bose-Bose,Fermi-Bose and Fermi-Fermi mixture. The interactions,which determine the stability and the dynamics of themixed-gas system, can be also tuned by changing a com-bination of a mixed gas or by using magnetic and opticalFeshbach resonances [3, 4, 5]. So far, Fermi-Bose mix-tures in the degenerate regime have been realized withvarious combinations of atoms:
