In quantum mechanics, I've learned that when there are incident photons with energy spectral density ##ρ(ω)## , two states system with ##E_i## and ##E_n## (##E_n > E_i##) goes through transition (absorption and emission) with transition rate [tex]Γ_{i→n}=Γ_{n→i}=\frac {2π}{ħ}|V_{ni}|^2ρ(E_n-E_i).[/tex]Is this detailed balance,? Wikipedia says that detailed balance definition is that "At equilibrium, each elementary process should be equilibrated by its reverse process."
Actually when I calculate transition rates with two states system, it seems that both emission and absorption process always have the same transition rate. Can I refer this as detailed balance? Thanks
