“…It was found that the entropy increases with the inter-quark distance, and the peak of the entropy emerges when the U-shaped string stretched between the touches the horizon of the black hole. Subsequently, there have many attempts to address the entropic force in this direction [22][23][24][25][26][27][28][29][30][31].…”

Previous studies have indicated that the peak of the quarkonium entropy at the deconfinement transition can be related to the entropic force which would induce the dissociation of heavy quarkonium. In this paper, we study the entropic force in a rotating hot and dense medium using AdS/CFT correspondence. It turns out that the inclusion of angular velocity increases the entropic force thus enhancing quarkonium dissociation, while chemical potential has the same effect. Furthermore, the results imply that the quarkonium dissociates easier in rotating medium compared to static case.

“…Thereafter, people used this method several times, for example, for a static [13,14] and moving quarkonium [15], and finite 't Hooft coupling correction [16]. For more studies in different backgrounds, see [17][18][19][20][21][22]. In Refs.…”

There are two important different mechanisms, the imaginary potential and entropic force, to investigate the dissociation of heavy quarkonia. In this paper, we calculate these two quantities for static and moving quarkonia in the rotating black 3-brane Type IIB supergravity solution dual to $$ {\mathcal {N}}=4 $$ N = 4 super Yang–Mills theory on the Coulomb branch (cSYM) at strong coupling. At $$ T\ne 0 $$ T ≠ 0 , there are two black hole branches: the large and small black hole branches. We investigate the effects of rotating parameter and rapidity for the static and moving quakonium at the large and small black hole branches. We find both mechanisms have the same results. In the large black hole branch: as $$ T/\Lambda $$ T / Λ and $$ \beta $$ β increase the thermal width decreases and so the suppression becomes stronger. In the small black hole branch: increasing $$ T/\Lambda $$ T / Λ leads to increasing the thermal width and the quarkonium dissociates harder but $$ \beta $$ β has an opposite effect.
