Many-Body Physics: Collective fermionic excitations in quark-gluon plasmas and cold atom systems

Abstract

In this talk I discuss collective excitations that carry fermion quantum numbers. Such excitations occur in the quark-gluon plasma and can also be produced in cold atom systems under special conditions.
