Hi,
Could anyone tell if there exists an identity [tex]a_k^\dagger = a_{-k}[/tex] because intuitively there should be no difference between creating a particle with momentum k and destroying a particle with momentum -k.
If true is it possible to show that from the definition [tex]a_k = \frac{1}{√V}∫e^{ikx} a(x)[/tex]?
