Back when I was working on my (never completed) dissertation, I would sometimes call up televangelists' hotlines and talk about my research. It was pretty amusing how they would initially try to steer the conversation to the God stuff but then give up as I kept relentlessly returning to my subject. Eventually they were reduced to "uh huh ... uh huh" but they couldn't just hang up on me because they weren't allowed to. I actually worked through some problems this way.

In programming, this is called 'Rubber Duck Debugging.'

The televangelists, in this case, were the rubber duck.

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?

[–] [email protected] 4 points 2 months ago (1 children)

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!

I run a small business. People in my spam folder have really high opinions of my business. They all want to invest or something... Mostly harvesting my LinkedIn profile for keywords.

I on the other hand for some reason seem to be in need of "high-quality" (yet very cheap) office chairs, according to my spam emails 🤷‍♀️

[–] [email protected] 1 points 2 months ago

I apparently also need the most comfortable chair ever. Which just makes me think of this C&H https://www.youtube.com/watch?v=AHKiGl02NmU

Ha, relatable!
