Abstract
Thermal pion fluctuations, in principle, can completely disorder
the phase of the quark condensate and thus restore chiral symmetry.
If this happens before the quark condensate melts, strongly-interacting matter
will be in the pseudogap state just above the chiral phase transition.
The quark condensate does not vanish locally and
quarks acquire constituent masses in the pseudogap phase, despite
chiral symmetry is restored.
