Description
Summary:A bstract We study the multi-boundary entanglement structure of the state associated with the torus link complement S 3 \T p,q in the set-up of three-dimensional SU(2) k Chern-Simons theory. The focal point of this work is the asymptotic behavior of the Rényi entropies, including the entanglement entropy, in the semiclassical limit of k → ∞ . We present a detailed analysis of several torus links and observe that the entropies converge to a finite value in the semiclassical limit. We further propose that the large k limiting value of the Rényi entropy of torus links of type T p,pn is the sum of two parts: (i) the universal part which is independent of n , and (ii) the non-universal or the linking part which explicitly depends on the linking number n . Using the analytic techniques, we show that the universal part comprises of Riemann zeta functions and can be written in terms of the partition functions of two-dimensional topological Yang-Mills theory. More precisely, it is equal to the Rényi entropy of certain states prepared in topological 2 d Yang-Mills theory with SU(2) gauge group. Further, the universal parts appearing in the large k limits of the entanglement entropy and the minimum Rényi entropy for torus links T p,pn can be interpreted in terms of the volume of the moduli space of flat connections on certain Riemann surfaces. We also analyze the Rényi entropies of T p,pn link in the double scaling limit of k → ∞ and n → ∞ and propose that the entropies converge in the double limit as well.
