If I look elektron with Hamiltonian
\hat{H}=-\frac{\hbar^2}{2m}\Delta_{\vec{r}}+V(\vec{r})
gde je
V(\vec{r})=\sum_{\vec{n}}W(\vec{r}-\vec{n})
This is Hamiltonian for "frosen" electron in apsolute zero. What is W look like in higher temperatures. Is it like
W(\vec{r}-\vec{n}+\vec{\hat{\zeta}}_{\vec{n}})
where \vec{\hat{\zeta}}_{\vec{n}} is phonon translation operator?
