Weakly Hadamard diagonalizable graphs and Quantum State Transfer

Darian McLaren, Hermie Monterde, Sarah Plosker

Hadamard diagonalizable graphs are undirected graphs for which the corresponding Laplacian is diagonalizable by a Hadamard matrix. Such graphs have been studied in the context of q…

The Complete Positivity of Symmetric Tridiagonal and Pentadiagonal Matrices

Lei Cao, Darian McLaren, Sarah Plosker

We provide a decomposition that is sufficient in showing when a symmetric tridiagonal matrix $A$ is completely positive. Our decomposition can be applied to a wide range of matrice…

Centrosymmetric Stochastic Matrices

Lei Cao, Darian McLaren, Sarah Plosker

We consider the convex set $Γ_{m, n}$ of $m \times n$ stochastic matrices and the convex set $Γ_{m, n}^{π} \subset Γ_{m, n}$ of $m \times n$ centrosymmetric stochastic matrices (stochastic…
