Title: Signed tensor densities and diagram budgets for the Thorp shuffle.

Abstract: We prove that a fixed number of coordinate sweeps of the Thorp shuffle on $2{}d$ cards makes the squared L2 distance of the full permutation density from uniform tend to zero as $d{}to{}infty$. In particular, the total-variation mixing time is ${}Theta(d)$ physical shuffles.
