Cayley graphs that have a quantum ergodic eigenbasis

Spectral Theory 2022-07-13 v1 Group Theory

Abstract

We investigate which finite Cayley graphs admit a quantum ergodic eigenbasis, proving that this holds for any Cayley graph on a group of size nn for which the sum of the dimensions of its irreducible representations is o(n)o(n), yet there exist Cayley graphs that do not have any quantum ergodic eigenbasis.
