Vector Coherent States on Clifford algebras

Abstract

The well-known canonical coherent states are expressed as an infinite series in powers of a complex number $z$ together with a positive sequence of real numbers $ρ(m)=m$. In this article, in analogy with the canonical coherent states, we present a class of vector coherent states by replacing the complex variable $z$ by a real Clifford matrix. We also present another class of vector coherent states by simultaneously replacing $z$ by a real Clifford matrix and $ρ(m)$ by a real matrix. As examples, we present vector coherent states on quaternions and octonions with their real matrix representations.
