- this is about coherent states
- Relevant Equations
- |z><z| = :exp(a-z)^\dagger (a-z):
i am reading this paper . in the definition 19 we have
|z><z| = :exp(a-z)^\dagger (a-z):
in the extansion the first term is the identity son it is not hart to find an eigenvector for the value 1. it is ok if the vector is annihilated by a. if is the case for the coherent grouns state. how to find an eigenstate for the value 0 ?
