The classical analogy between knots and primes motivates the study of Alexander polynomials through an arithmetic perspective. In this article we study the two-parameter family of torus knots and links T, ₐ and analyze the asymptotic behaviour of the zeros of their Alexander polynomials Δ, ₐ (t), defined with respect to the total linking number covering. We prove that as p, q these zeros become equidistributed on the unit circle and derive an explicit formula for the limiting frequency with which primitive r-th roots of unity appear. To capture finer statistical information, we introduce the moment sequence of the zero distribution and compute its generating function in closed form. We further examine the Iwasawa theory of the corresponding branched covers, determining the Iwasawa invariants. The logarithmic Mahler measure of Δ, ₐ (t) vanishes identically and the associated homological growth in towers of abelian covers of S³ branched along T, ₐ is subexponential.
