Infrared Effective Dual QCD at Finite Temperature and Densities

An infrared effective version of dual QCD based on the topological structure of non-Abelian gauge theories has been discussed and its extension to finite temperature and baryon densities has been analyzed to explore the dynamics of quark-hadron phase transition and QGP. The topologically effective magnetic symmetry-based dual QCD has been discussed for its color confining aspects, and its thermal version has been developed using the grand canonical ensemble formalism. The construction of the equation of state within the dual QCD framework has been shown to lead to critical parameters and critical points in the phase diagram for a QGP phase transition. For quark matter at finite baryon densities, various thermodynamical profiles have been shown to indicate a weak first-order phase transition with some critical end points.
