“…Second, it has been reported that noncentral collisions tend to deposit a high angular momentum in the quark gluon plasma (QGP) generated in heavy ion collisions, and such angular momentum may give rise to significant observable effects in QGP [29−33]. To date, various observables with respect to QGP have been studied under the influence of angular momentum from holography, such as the jet quenching parameter [34,35], drag force [36−38], energy loss [39−41], confinement/deconfinement [42,43], and running coupling constant [44]. Other related studies can be found in [45−51].…”

We perform the potential analysis for the holographic Schwingereffect in spinning Myers-Perry black holes. We compute thepotential between the produced pair by evaluating the classicalaction of a string attaching on a probe D3-brane sitting at anintermediate position in the AdS bulk. It turns out thatincreasing the angular momentum reduces the potential barrier thusenhancing the Schwinger effect, consistent with previous findingsobtained from the local Lorentz transformation. In particular,these effects are more visible for the particle pair lying in thetransversal plane compared with that along the longitudinalorientation. In addition, we discuss how the Schwinger effectchanges with the shear viscosity to entropy density ratio atstrong coupling under the influence of angular momentum.

Within the framework of the Einstein-Maxwell-dilaton model, which incorporates information on the equation of state and baryon number susceptibility from lattice results, we have conducted a comprehensive analysis of the potential energy, running coupling, and dissociation time for heavy-quark–antiquark pairs using gauge/gravity duality. This study encompasses various systems, including pure gluon systems, 2-flavor systems, 2+1-flavor systems, and 2+1+1-flavor systems under finite temperature and chemical potential. The results reveal that the linear component of the potential energy diminishes as the flavor increases. It is also found that our results are extremely close to the recent lattice results for 2+1-flavors at finite temperature. Moreover, we have thoroughly investigated the dissociation distance and effective running coupling constant of quark-antiquark pairs to gain a comprehensive understanding of their behavior across various flavors. Finally, we have examined real-time dynamics of quark dissociation. The findings indicate that the dissociation time of quark-antiquark pairs is dependent on temperature, chemical potential, and flavor of the systems. Published by the American Physical Society 2024
