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 at around 10^6Hz.

I 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:

1. The coupling between the two is very weak.
2. Correlations between the two decay so fast that this can be considered instantaneous.

The later produces white noise.

I work on quantum systems coupled to noisy environments (noisy as in causing random fluctuations). Atoms coupled to a light field are my specialty. Anyway, I just got invited by a predatory journal in the field of acoustics, vibrations and noise?!

Except they know that they would have to cover the apple in a thin metallic layer for it to be observable under an electron microscope :D

Thank god the universe is purely described using linear algebra.

Lovely picture! Either I don’t get the meme part or I can’t find Saddam.
