Abstract

The entropic force has been recently argued to be responsible for dissociation of heavy quarkonia. In this paper, we analyze R2R^2 corrections and R4R^4 corrections to the entropic force, respectively. It is shown that for R2R^2 corrections, increasing λGB\lambda_{GB} (Gauss-Bonnet factor) leads to increasing the entropic force. While for R4R^4 corrections, increasing λ\lambda ('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\eta/s, at strong coupling.
