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 left science a long time ago and recently got such an invitation from a Q3 engineering journal on aerodynamics (I worked on quantum systems as well, hi).
I took 3 books on aerodynamics and wrote a paper citing and compiling the texts; adding some chatgpt noise. Really nothing new, just some intermediate equations. The reference section contains these 3 books and 4 recent papers for the introductory part. I sent it several days ago and am awaiting the review.
Hey, noise is noise. What color is yours, white, pink or blue?
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:
- 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 at around 10^6Hz.
