montechristo@feddit.org 2 days agoI describe the atoms using a so called Lindblad master equation. The atoms are kept in this description, but the light field is eliminated using two assumptions:
- The coupling between the two is very weak.
- Correlations between the two decay so fast that this can be considered instantaneous.
The later produces white noise.

That’s cool
In most fields " so fast that’s instantaneous" is pretty fast, but in nuclear and quantum physics that’s a whole new level.
What is the order of magnitude of your " too fast ”? I will invert that to state the bandwidth in Hertz.

Typical transition frequencies between two levels of an atom are 10^15Hz. The coupling between atoms and light is on the order of the decay rate at which photons are transmitted, which sits around 10^6Hz.
