Abstract
At high density, strongly interacting matter is believed to take the form of a quark gluon plasma in which the quarks and gluons are not confined within hadrons and chiral symmetry is maintained. The transition from the quark-gluon plasma state to the low density hadronic phase is of interest in connection with early universe cosmology, heavy ion collisions and, possibly, neutron star interiors. We will consider here the situation if the transition is of first order and bubbles of the low density phase are nucleated within a supercooled plasma. A transition front can move either supersonically or subsonically relative to the medium ahead (corresponding to detonation or deflagration solutions respectively)1 and we have previously presented a comparison of these two types of front based on an analysis of their associated characteristic structure2. Deflagrations require smaller supercooling and it seems likely to be these which occur in practice. An important feature of deflagrations is that the rate at which energy crosses the interface (the “transition rate”) cannot be calculated directly from the hydrodynamic equations but must be supplied as a separate condition derived from considerations of the transformation process. This further condition places constraints on the possible values of fluid parameters on either side of the interface. We will here describe the situation for planar symmetry and vanishingly small baryon number density.
