Alright, I'm sure I'm missing something extremely simple, but in Griffiths (and another text I'm reading) coherent states are mentioned as eigenfunctions of the annihilation operator.
I just don't understand:
a) how you can have an eigenfunction of the annihilation operator (other than |0>) if the whole point is it knocks you down a level from |n> to |n-1>
b) why the creation operator is described as not having ay eigenfunctions if you can have eigenfunctions of the annihilation operator
any help would be great, thanks!
