“…The result that the critical temperature of the confinement/deconfinement transition decrease with increasing angular velocity is in agreement with recently study of the confinement/deconfinement transition phase in rotating QCD using phenomenological models [33][34][35]. The same behaviour was found also in Nambu-Jona-Lansinio model [36], in which the critical temperature in rotating QCD decreases due to suppression of the chiral condensate.…”

“…On the other hand, the simulations of relativistic rotation on the confinement/deconfinement phase transition in gluodynamics lattice [32], using different types of boundary conditions (Open, Periodic and Dirichlet), found that the critical temperature increases with increasing angular velocity for all boundary conditions and all lattice parameters used in the calculations, showing up an opposite behaviour if compared to our result and to the other models [33][34][35][36] cited above. However, the same authors of [32] have recently presented the first lattice results in [37] (preliminary) for the confinement/deconfinement phase transition taking into account dynamical fermions.…”

Non-central heavy ion collisions lead to the production of a quark gluon plasma with angular momentum. We investigate, using holographic AdS/QCD models, how does rotation of the medium affects the confinement/deconfinement transition temperature T c . In holographic models, this transition is represented by a Hawking-Page process involving two asymptotically anti-de Sitter spaces. The plasma is represented here by extending the holographic approach to anti-de Sitter spaces with cylindrical symmetry. Then, the rotation of the medium is introduced through a Lorentz boost. We consider hard and soft wall AdS/QCD models. In both cases we find it out that, as the angular velocity ω increases, T c decreases, showing that the plasma rotation catalyses the confinement/deconfinement transition.

In this work, we investigate the melting of charmonium states within a holographic QCD model in the context of Einstein-Maxwell-Dilaton (EMD) theory. In the dual field theory, the model describes the heavy mesons inside a finite temperature and density medium. First, we calculate the spectrum at zero temperature. Then, at finite temperature, we obtain the spectral functions, where the heavy vector meson are represented by peaks. We show that the charmonium melts down at temperatures above the confinement/deconfinement temperature of the quark-gluon plasma. We also observe that the chemical potential speeds up the melting process. This finding is in agreement with results previously reported in the literature. In the gravitational side of the theory we solve the perturbation equations in the hydrodynamics limit. From this result we read off the diffusion coefficient by comparing the dispersion relation against the corresponding result obtained in the dual field theory. We also investigate the behavior of the diffusion coefficient as a function of the temperature. The perturbation equations are solved numerically, in order to get the quasinormal frequencies. We report the emergence of a new mode whose real part increases rapidly at a certain value of the chemical potential while its imaginary part decreases with the increasing of the chemical potential. Finally, by comparing against results obtained in the conformal plasma, we observe that the real part of the frequency increases, while the imaginary part decreases when we consider the non-conformal plasma.

“…It is defined by requiring S(p, t) and S 0 (t) to satisfy the matching condition (4.62), which the heavy quark rotational viscosity, λ s in terms of the source or spin correlation functions -is applicable even in the strong-coupling regime, where we have the AdS/CFT correspondence as another theoretical tool [56][57][58][59], and in particular the methods first developed for holographic spin liquids in ref. [60].…”

We compute the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma to leading-log order in the coupling constant g. The spin relaxation rate Γ s in spin hydrodynamics is shown to be Γ s ∼ g 4 log(1/g)T (T /M ) 2 in the heavy-quark limit T /M 1, which is smaller than the relaxation rate of other non-hydrodynamic modes by additional powers of T /M . We demonstrate three different methods to evaluate the spin relaxation rate: 1) the Green-Kubo formula in the spin hydrodynamic regime, 2) the spin density correlation function in the strict hydrodynamic limit, and 3) quantum kinetic theory of the spin distribution function in momentum space. We highlight the interesting differences between these methods, while they are ultimately connected to each other by the underlying Ward-Takahashi identity for the non-conserved spin density.
