05C50 Online Seminar: Thomás Jung Spier
Topic
No perfect state transfer in trees with more than 3 vertices
Speakers
Details
The adjacency matrix A of a graph G is the Hamiltonian for a continuous-time quantum walk on the vertices of G. If u and v are distinct vertices in G, we say perfect state transfer from u to v occurs if there is a time t such that the (u,v)-entry of exp(iAt) has absolute value 1. In this talk, we show that the only trees that admit perfect state transfer are P_2 and P_3. This is joint work with Gabriel Coutinho and Emanuel Juliano.
A recording of the talk will be shared on the main website. You may email the speaker for their slides.
