• Abstract: The recent developments in the study of topological multi-boundary entanglement in the context of 3d Chern-Simons theory (with gauge group $G$ and level $k$) suggest a strong interplay between entanglement measures and number theory. The purpose of this note is twofold. First, we conjecture that the 'sum of the negative powers of the quantum dimensions of all integrable highest weight representations at level $k$' is an integer multiple of the Witten zeta function of $G$ when $k \to \infty$. This provides an alternative way to compute these zeta functions, and we present some examples. Next, we use this conjecture to investigate number-theoretic properties of the R\'enyi entropies of the quantum state associated with the $S^3$ complement of torus links of type $T_{p,p}$. In particular, we show that in the semiclassical limit of $k \to \infty$, these entropies converge to a finite value. This finite value can be written in terms of the Witten zeta functions of the group $G$ evaluated at positive even integers.

  We show that the non-integer $n$ results for $langlephinrangle$ or $langle(iphi)nrangle$ are consistent with those from the wave function approach. In the $mathcalPT$ invariant case, the existence of $langle(iphi)nrangle$ with non-integer $n$ allows us to bootstrap the non-Hermitian theories with non-integer powers.

  The observables associated with a quantum system $S$ form a non-commutative algebra $mathcal A_S$. It is assumed that a density matrix $rho$ can be determined from the expectation values of observables. Abelian algebras do not have inner automorphisms, so the measurement apparatus can determine mean values of observables.
