Holographic entropy and realtime dynamics of quarkonium dissociation in nonAbelian plasma
Abstract
The peak of the heavy quark pair entropy at the deconfinement transition, observed in lattice QCD, suggests that the transition is effectively driven by the increase of the entropy of bound states. The growth of the entropy with the interquark distance leads to the emergent entropic force that induces dissociation of quarkonium states. Since the quarkgluon plasma around the transition point is a strongly coupled system, we use the gaugegravity duality to study the entropy of heavy quarkonium and the realtime dynamics of its dissociation. In particular, we employ the improved holographic QCD model as a dual description of large N_{c} YangMills theory. Studying the dynamics of the fundamental string between the quarks placed on the boundary, we find that the entropy peaks at the transition point. We also study the realtime dynamics of the system by considering the holographic string falling in the black hole horizon where it equilibrates. As a result, in the vicinity of the deconfinement transition, the dissociation time is found to be less than a fermi, suggesting that the entropic destruction is the dominant dissociation mechanism in this temperature region.
