Dynamical holes in the quark-gluon plasma

Abstract

A high-temperature quark-gluon plasma is shown to have twice as many fermionic modes as at zero temperature. Besides propagating quarks and antiquarks there are also propagating quark holes and antiquark holes. The holes are generated dynamically (i.e., without any chemical potentials) and show many similarities to Cooper pairing in superconductivity. They provide some unique experimental signals for the existence of the quark-gluon plasma.
