Abstract In their supercritical state simple fluids are generally thought to assume a homogeneous phase throughout all combinations of pressures and temperatures, although various response functions or transport properties may exhibit anomalous behavior, characterizing point as either more gas-like liquid-like, respectively. While large body results has been compiled in the last two decades reg...

We consider a modification of the contact process incorporating higher-order reaction terms. The original contact process exhibits a non-equilibrium phase transition belonging to the universality class of directed percolation. The incorporated higher-order reaction terms lead to a non-trivial phase diagram. In particular, a line of continuous phase transitions is separated by a tricritical poin...

We continue to develop further the bag-type Double Phase Transition Model (DPTM) for transformation of Quark-Gluon Plasma (QGP) to normal hadronic matter (H-phase). The model is based on the assumed existence of an intermediate Q phase composed by massive constituent quarks and pions (as Goldstone bosons) 5, 6. In the present paper the problem of entropy S and baryon number N B conservation in ...
