报告摘要：It is well known that almost all elementary quantum many-body particles in nature are divided fundamentally into two classes, i.e., bosons and fermions, in terms of the spin quantum numbers. Ground states of quantum bosons were investigated widely over the past few decades. In this talk we focus on ground states of mass subcritical quantum Fermi systems with attractive interactions. The existence of ground states is discussed in terms of the strengthen for the system's interactions, based on which we further investigate the mass concentration behavior of ground states.
