Hello! My question is motivated by this paper (also attached below). They are measuring the mass of a molecular ion in a Penning trap, and they are able to see a difference due to the fact that the molecule gets polarized (the motion is classical and non-relativistic). I was able to derive their...

@Vanadium 50 @PeterDonis I don't work in this field so I don't know the whole extent of these experiments, but this is a relatively recent paper looking at the interaction between spin and gravity. @Vanadium 50 as I already said several times, I didn't claim that people are looking for frame...

I am not sure I understand what you mean. As I said, people are searching experimentally for quantum spin interacting with gravity. Whether you think of it as actually rotating or not doesn't matter too much, the point is that there is an interaction. My question is simply if this interaction...

I am not sure I understand. People are searching experimentally for quantum spin-gravity interactions. So there must be at least attempts to describe a quantum spinning object in gravity. I don't see why doing the jump from there and asking about frame dragging would be necessary so difficult...

But I mentioned in the initial post that I am only interested in orbital, not intrinsic spin, this is why I mentioned spherical harmonic (not sure if spherical harmonics can also describe spin, sorry if that is the case, but I meant only orbital angular momentum which has an easier classical...

I am not interested in the way to measure it, just how you'd go about calculating it theoretically. Also, as I mentioned above, I had in mind a rotating molecule, not an electron (still a small effect, but given that the nuclei are rotating it should be many orders of magnitude higher).

What do you mean by classical? The wavefunction of hydrogen does have a spherical harmonics, which corresponds to a given angular momentum.

I am interested more theoretically than actually measuring it. I had in mind more like, for example, a molecule rotating, but a hydrogen atom works, too (but in that case is the electron doing most of the spinning, not the nucleus, so the effect would be even smaller).

I know we don't have a full theory trying to combine both, but I was wondering if there are any papers trying to look at this phenomenon (e.g. Hawking radiation is using both GR and QFT, without us having a full theory combining both, so I was wondering if anyone tried to look at this phenomenon...

Hello! Is there any work which looks at the frame dragging effect due to a rotating quantum object (e.g. in an eigenstate which is a spherical harmonic)? I would appreciate any reference on that.

Hello! I am reading about laser cooling, and I see people talking about the Frank Condon factors. It seems to be just a vibrational overlap integral, but I found different definitions in terms of whether is just the integral or its square (the difference is huge, so it should matter). What is...

@Baluncore @davenn Sorry I didn't mention microwaves (indeed the other post is related, but I wanted to keep them separated). I wanted to check if I can use an insulator in general, without further complicating the questions with the microwaves, but probably that would have actually helped. The...

Actually this was one of the questions I have. In my case I don't care about the speed of the voltage distribution i.e. I keep the plates at a fixed voltage for days or weeks after I apply the voltage. While an insulator won't have the same voltage on its whole surface immediately, would it...

I am still exploring options (and I would really appreciate any advice about that), but the main reason for now is that we want to send microwaves along the beamline (i.e. along the direction of motion of the ions) and the 2 parallel aluminum plates are along this direction, so they would act as...

Currently we have a power supply that can produce up to 5 kV and we just connect it to the aluminum plate with a wire. I was wondering if I can do the same with an insulating plate.
