abstract
We study Wilson loops in holographic duals of the $\mathcal{N}=4$ SYM quark-gluon plasma. For this we consider the Schwarzschild-$AdS_5$ and Kerr-$AdS_5$ black holes, which are dual to the non-rotating and rotating QGPs, correspondingly. From temporal Wilson loops we find the heavy quark potentials in both backgrounds. For the temperature above the critical one we observe the Coulomb-like behaviour of the potentials. We find that increasing the rotation the interquark distance decreases, we also see that the increase of the temperature yields the similar behaviour. Moreover, at high temperatures values of the potentials in Kerr-$AdS_5$ are close to that one calculated in the Schwarzschild-$AdS_5$ black hole. We also explore holographic light-like Wilson loops from which the jet-quenching parameters of a fast parton propagating in the QGP are extracted. We find that the rotation increases the value of the jet-quenching parameter. However, at high temperatures the jet-quenching parameters have a cubic dependence on the temperature as for the AdS black brane.

Gluon polarization contribution to the spin alignment of vector mesons from holography
A soft-wall holographic QCD model with a rotation-dependent gluon field predicts that rotation enhances the spin alignment of phi and rho mesons at high pT while J/psi stays nearly unaffected.

Holographic QCD phase diagram for a rotating plasma in the Hawking-Page approach
In the hard wall and soft wall AdS/QCD models, increasing plasma rotation lowers the deconfinement temperature and lowers the zero-temperature critical quark chemical potential.
