    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?!

        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.

          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 at around 10^6Hz.

      I look forward to your original contribution, “Atomic Noise: Acoustic Vibrations at Nanomolecular Scale.” Reviewer 2 can suck it, 'cause this one’s about to blow up!
