Bose–Fermi mixed condensates of atomic gas with boson–fermion quasi-bound state

Abstract

The phase structures of the boson–fermion (B and F) mixed condensates of atomic gas are discussed under the existence of boson–fermion composite fermions (quasi-bound states) BF from the equilibrium in B+F↔BF. Especially we discuss the competitions between the BF degenerate states and the Bose–Einstein condensates (BEC) in low- T. The criterion for the BEC realization is obtained from the algebraically derived phase diagrams at T=0.
