“…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.

“…After [64], several times the entropic force was calculated by using the holographic method. For example, the entropic force was studied for a moving [65] and a rotating quarkonium [66], and a moving dipole in a Yang-Mills like theory [67]. Also, the chemical potential effect [68], R 2 and R 4 corrections [69] and the effect of the deformation parameter [70] on the entropic force are investigated.…”

The imaginary potential and entropic force are two important different mechanisms to characterize the dissociation of heavy quarkonia. In this paper, we calculate these two quantities in strongly coupled theories with anisotropic Lifshitz scaling and hyperscaling violation exponent using holographic methods. We study how the results are affected by the hyperscaling violation parameter $$ \theta $$ θ and the dynamical exponent z at finite temperature and chemical potential. Also, we investigate the effect of the chemical potential on these quantities. As a result, we find that both mechanisms show the same results: the thermal width and the dissociation length decrease as the dynamical exponent and chemical potential increase or as the hyperscaling violating parameter decreases.

“…Hashimoto et al, calculating for the first time the entropic force associated with the heavy quark pair using the AdS/CFT correspondence [28], showed that the entropy increases with the inter-quark distance and the peak of the entropy depends on the nature of deconfinement and emerges near the transition point. After those, the entropic force was calculated by using this method several times, for example, for a moving [29] and rotating quarkonium [30], a moving dipole in a Yang-Mills like theory [31], for the chemical potential effect [32], R 2 and R 4 corrections [33] and for the effect of deformation parameter [34].…”

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.
