Abstract:

It is known that almost all elementary quantum many-body particles in quantum physics can be divided fundamentally into two classes, i.e., bosons and fermions. Ground states of quantum bosons were investigated widely over the past few decades. In this talk we discuss ground states of mass subcritical quantum Fermi systems with attractive interactions. The existence of ground states is addressed in terms of the strengthen for the system's interactions, based on which we further investigate the mass concentration behavior of ground states.
