Spontaneous emission from a two-level atomTwo-level atom with states |1〉, |0〉H = ω 02 σ z + ∑ Qγ Q(σ + a Q + σ − a † Q)+ ∑ Qω Q a † Q a Q. (14)Pauli matrices, photon creation operators a † Q .Not too much can be learned here: transient process, exponentiallydecay<strong>in</strong>g probability.We want to describe stationary processes ‘driven spontaneousemission’ (resonance fluorescence).Analogy to tunnel<strong>in</strong>g of a s<strong>in</strong>gle electron from a s<strong>in</strong>gle level <strong>quantum</strong>dot.
