We investigate the properties of nuclear matter at the first-order phase transitions (FOPT) such as liquid-gas phase transition and hadron-quark phase transition. As a general feature of the FOPT of matter consisting of many species of charged particles, there appears a mixed phases with geometrical structures called "pasta" due to the balance of the coulomb repulsion and the surface tension between two phases. The equation of state (EOS) of mixed phase is different from the one obtained by a bulk application of the Gibbs conditions or by the Maxwell construction due to the effects of the non-uniform structure. We show that the charge screening and strong surface tension make the EOS close to that of the Maxwell construction. The thermal effects are elucidated as well as the above finite-size effects.

Replica symmetry breaking for the mean-field Potts glass model in a field

The mean-field p-state Potts glass model is studied in the presence of a field. As effective ferromagnetic interaction in the Potts glass model grows as temperature decreases, uniform part of the interaction is set to make effective ferromagnetic interaction zero at the continuous glass transition temperature without field. Replica symmetry breaking pattern is obtained analytically near the freezing of the transverse components for small fields. Replica symmetry breaking is continuous for p3.4, which is similar to the symmetry breaking for the Ising spin glass model. One step replica symmetry breaking is stable for 4.6p3.4. The transition to the transverse freezing phase is discontinuous for p4.6. This threshold is larger than 4 that is the threshold for the zero field case. These results show that qualitative feature of the transition in a field is similar to that without field if the number of the Potts components is shifted accordingly.
