Title: Average Mixing Matrices of Trees and Stars
Speaker: Paula Kimmerling Affiliation: Washington State University Zoom: Contact Soffia ArnadottirAbstract:
We define the average mixing matrix (AMM) of a continuous-time quantum walk on a graph using the orthogonal projections onto the eigenspaces of the adjacency matrix A. From there, one of the properties that has been studied is the rank of the AMM. This is easiest to do if the eigenvalues of A are simple, and we’ll review some of the results on this from Coutinho et. al. (2018).
