Abstract
The entropic force has been recently argued to be responsible for dissociation of heavy quarkonia. In this paper, we analyze R2 corrections and R4 corrections to the entropic force, respectively. It is shown that for R2 corrections, increasing λGB (Gauss-Bonnet factor) leads to increasing the entropic force. While for R4 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, ηâs, at strong coupling.
