“…3 Since these gauge and diffeomorphism invariant combinations fall within different representations of SO (3), they cannot mix at the linear level and each one of these pertur- bations will satisfy a decoupled equation of motion. 4 As discussed in [56], due to SO(3) symmetry, each spatial component of the Maxwell field perturbation, a, satisfies the same decoupled differential equation and, therefore, we may take without loss of generality, a ≡ a x , such that the corresponding equation of motion reads [56],…”

Dynamical versus equilibrium properties of the QCD phase transition: A holographic perspective

We employ an Einstein-Maxwell-Dilaton (EMD) holographic model, which is known to be in good agreement with lattice results for the QCD equation of state with (2 + 1) flavors and physical quark masses, to investigate the temperature and baryon chemical potential dependence of the susceptibilities, conductivities, and diffusion coefficients associated with baryon, electric, and strangeness conserved charges. We also determine how the bulk and shear viscosities of the plasma vary in the plane of temperature and baryon chemical potential. The diffusion of conserved charges and the hydrodynamic viscosities in a baryon rich quark-gluon plasma are found to be suppressed with respect to the zero net baryon case. The transition temperatures associated with equilibrium and non-equilibrium quantities are determined as a function of the baryon chemical potential for the first time. Because of the crossover nature of the QCD phase transition even at moderately large values of the chemical potential, we find that the transition temperatures associated with different quantities are spread in the interval between 130 − 200 MeV and they all decrease with increasing baryon chemical potential.

Abstract:We investigate temperature dependent behavior of various transport coefficients in a dynamical holographical QCD model. We show the nontrivial temperature dependent behavior of the transport coefficients, like bulk viscosity, electric conductivity as well as jet quenching parameter, and it is found that all these quantities reveal information of the phase transition. Furthermore, with introducing higher derivative corrections in 5D gravity, the shear viscosity over entropy density ratio also shows a valley around phase transition, and it is found that the shear viscosity over entropy density ratio times the jet quenching over temperature cubic ratio almost remains as a constant above phase transition, and the value is two times larger than the perturbative result in Phys.Rev. Lett.99.192301(2007).

“…To get a fields configuration which is both consistent with the equation of motions and realizes the linear Regge trajectory, dynamical soft-wall models were constructed by introduce a dilaton potential consistently [10,11]. On the other hand, the Einstein-dilaton and Einstein-Maxwell-dilaton models have been widely studied numerically [12][13][14][15][16] to investigate the thermodynamical properties and explore the phase structure in QCD. Recently, by the potential reconstruction method, analytic solutions have been obtained in the Einstein-dilaton model [17] as well as in the Einstein-Maxwell-dilaton model [16,18].…”

Abstract:We consider the Einstein-Maxwell-dilaton system with an arbitrary kinetic gauge function and a dilaton potential. A family of analytic solutions is obtained by the potential reconstruction method. We then study its holographic dual QCD model. After fixing the kinetic gauge function by requesting the linear Regge spectrum of mesons, we calculate the free energy to obtain the phase diagram of the holographic QCD model.
