Impact of different extended components of mean-field models on transport coefficients of quark matter and their causal aspects

Estimation of transport coefficients of dense hadronic and quark matter

“…These estimations of thermodynamical quantity -enthalpy density, and transport coefficients -shear viscosity, electrical conductivity at T = 0 and µ = 0 domain can be compared with the estimations thermodynamics and transport coefficients at T = 0 and µ = 0 domain, given in Ref. [39] and references therein. The quark-hadron transition at T = 0 and µ = 0 domain is understood by estimating thermodynamics of massless quark gluon plasma (QGP) and hot pion gas for high and low temperature zones respectively.…”

“…Now, with the help of standard relaxation time approximation (RTA) methods of Boltzmann transport equation, one can get [39] δf…”

“…q = 0, e for neutron and proton. Here, the RTA methods of Boltzmann transport equation will again help us to give the form of δf N [39]:…”

“…At very high T , these limiting values can be reached. As we go from high to low T , the values of thermodynamical quantities and transport coefficients will decrease and their maximum decrement will be noticed around quark-hadron transition temperature [39]. Here we are interested to find similar kind of graphs along baryon density axis.…”

“…The present work is aimed to probe this hadron-quark phase transition via transport coefficients estimations in this high baryon density and low/vanishing temperature domain of QCD phase diagram. The motivation of this kind of investigation comes from the equivalent pattern of LQCD thermodynamics [19,20] and normalized transport coefficients [39] in the high temperature and low/vanishing baryon density domain of QCD phase diagram.…”
