Abstract

We consider gas of massless fermions at certain temperature T and acceleration a. We find a second order phase transition at temperature T approaching the Unruh temperature TU. The implications for hadronization of the quark-gluon plasma produced in heavy-ion collisions (HIC) and for black-hole physics are discussed. In particular, this novel phase transition may be associated with thermalization in HIC, indicating its analogy with falling into a black hole.
