Links with nontrivial Alexander polynomial which are topologically concordant to the Hopf link

Abstract

We give infinitely many $2$-component links with unknotted components which are topologically concordant to the Hopf link, but not smoothly concordant to any $2$-component link with trivial Alexander polynomial. Our examples are pairwise non-concordant.
