How to compute $\chi_1$, a Lorentzian absorption in the following paper?
I have the following paper:
https://arxiv.org/abs/1508.01213
on the third page, where they take: $$\chi_2(\omega)= \frac{-k\gamma}{(\omega-\omega_0)^2+\gamma^2},$$ I don't see how to explicitly comput …

A question on the transition matrix. (algebraic derivation)
I am trying to follow the derivation of the following identity:
$$[\epsilon -H_0+i\eta]^{-1}T = [\epsilon - H +i\eta]^{-1}U$$
where $T$ is the transition matrix and $U$ is the potential caused by th …
