“…The energy loss of rotating string has been discussed in [79][80][81][82]. In [83,84], the energy loss of rotating quarks with angular velocity has been discussed. Drag force in Kerr black hole can be seen in [85,86].…”

We consider the holographic QCD model with a planar horizon in the D dimensions with different consistent metric solutions. We investigate the black hole thermodynamics, phase diagram and equations of state (EoS) in different dimensions. The temperature and chemical potential dependence of the drag force and diffusion coefficient also have been studied. From the results, the energy loss of heavy quark shows an enhancement near the phase transition temperature in D dimensions. This finding illustrates that the energy loss of heavy quark has a nontrivial and non-monotonic dependence on temperature. Furthermore, we find the heavy quark may lose less energy in higher dimension. The diffusion coefficient is larger in higher dimension.

“…Actually, AdS/CFT can be as insightful in this issue and various observables or quantities have already been studied. Such as drag force [32][33][34], jet quenching parameter [35,36], energy loss [37][38][39], phase transition [40] and free energy [41].…”

“…Certainly, there is little hope of obtaining a significant correction owing to the angular velocity in current experiments; however, this may be observed in the near future. Moreover, AdS/CFT can be as insightful within this is-sue, and various observables and quantities have already been studied, such as drag force [32][33][34], the jet quenching parameter [35,36], energy loss [37][38][39], phase transition [40], and free energy [41]. Inspired by this, we investigate the effect of angular velocity on the Schwinger effect in a deformed AdS black-hole background.…”

We perform the potential analysis for the holographic Schwinger effect in a rotating deformed AdS black-hole background. We calculate the total potential of a quark-antiquark ($Q\bar{Q}$) pair in an external electric field and evaluate the critical electric field from Dirac-Born-Infeld (DBI) action. It is shown that the inclusion of angular velocity decreases the potential barrier thus enhancing the Schwinger effect, opposite to the effect of the confining scale. Moreover, by increasing angular velocity decreases the critical electric field above which the pairs are produced freely without any suppression. Furthermore, we conclude that producing $Q\bar{Q}$ pairs would be easier in rotating medium.
