Pretty good quantum state transfer via transcendental edge weights
Addison Ballif, Mark Kempton, James B. Larsen +3
We prove that if we take a rooted product of a circulant graph with universal perfect state transfer with a path of fixed length whose end edge is weighted with a transcendental nu…

Unicyclic graphs and the inertia of the distance squared matrix
Christian Howell, Mark Kempton, Kellon Sandall +1
A result of Bapat and Sivasubramanian gives the inertia of the distance squared matrix of a tree. We develop general tools on how pendant vertices and degree 2 vertices affect the…
