In general we can say that the thermal width of quarkonia corresponds to imaginary part of it's potential. Gravity dual of theories give explicit form of potential as V QQ . Since there is an explicit formula for ImV QQ one can consider different gravity duals and study the results of contribution of various parameters. Variable gravity duals of moving pair in plasma have different results for potential. Our paper shows that deformation parameter c in warp factor leads to new results that we present them for arbitrary angles of the pair with respect to it's velocity. We compare our results with the case that no deformation parameter is in metric background. We will see that the thermal width of the pair increases with increasing deformation parameter. Also, for nonzero values of deformation parameter the pair feels moving plasma in all distances. In addition our results indicate that contribution of deformation parameter leads to larger dissociation length for the moving pair reverse to the effect of the pair's velocity in the plasma.

For a moving heavy quark antiquark (QQ) in a quark gluon plasma (QGP), we use gauge/gravity duality to study both real and imaginary parts of the potential ($$ \operatorname{Re}{V}_{Q\overline{Q}} $$ Re V Q Q ¯ and $$ \operatorname{Im}{V}_{Q\overline{Q}} $$ Im V Q Q ¯ respectively) in a gluon condensate (GC) theory. The complex potential is derived from the Wilson loop by considering the thermal fluctuations of the worldsheet of the Nambu-Goto holographic string. We calculate $$ \operatorname{Re}{V}_{Q\overline{Q}} $$ Re V Q Q ¯ and $$ \operatorname{Im}{V}_{Q\overline{Q}} $$ Im V Q Q ¯ in both cases where the axis of the moving $$ Q\overline{Q} $$ Q Q ¯ pair is transverse and parallel with respect to its direction of movement in the plasma. Using the renormalization scheme for the $$ \operatorname{Re}{V}_{Q\overline{Q}} $$ Re V Q Q ¯ , we find that the inclusion of GC increases the dissociation length while rapidity has the opposite effect. While for the $$ \operatorname{Im}{V}_{Q\overline{Q}} $$ Im V Q Q ¯ , we observe that by considering the effect of GC, the $$ \operatorname{Im}{V}_{Q\overline{Q}} $$ Im V Q Q ¯ is generated for larger distance thus decreasing quarkonium dissociation, while rapidity has opposite effect. In particular, as the value of GC decreases in the deconfined phase, the $$ \operatorname{Im}{V}_{Q\overline{Q}} $$ Im V Q Q ¯ is generated for smaller distance thus enhancing quarkonium dissociation, and at high temperatures it is nearly not modified by GC, consistent with previous findings of the entropic force.

Higher derivative corrections to the entropic force from holography

The entropic force has been recently argued to be responsible for dissociation of heavy quarkonia.In this paper, we analyze R 2 corrections and R 4 corrections to the entropic force, respectively. It is shown that for R 2 corrections, increasing λGB (Gauss-Bonnet factor) leads to increasing the entropic force. While for R 4 corrections, increasing λ ('t Hooft coupling) leads to decreasing the entropic force. Also, we discuss how the entropic force changes with the shear viscosity to entropy density ratio, η/s, at strong coupling.
