I'm convinced. Thank you very much! :)

Very nice! Didn't know about this effect. Our discussion already elucidated some issues to me but I'm still a bit confused. I am partially convinced that we should see Larmor precession in macroscopic bodies and I see your argument about the relevance of the size of the macroscopic system. It...

Sorry for the absence. I was out of town due to work. I'm going to have look and provide you the feedback. :)

Let's work without gravity as you said. The mass is irrelevant in that case, right? :) Would you confirm that your assumption of proportionality between the magnetic moment and angular momentum is valid for macroscopic bodies? As I said before, my question boils down to this one. I really...

That's exactly the subject from where this came from, nuclear magnetic resonance. :) For elementary particles we know from experience that the total angular momentum and magnetic moment are proportional. Futhermore, we also know from experience that the proportionality constant (the...

Hey there! I would really appreciate if someone could help me with the following problem. I didn't find it anywhere (textbooks, web...). Not only currents but also magnetized bodies possesses magnetic moment. I know that if the magnetized body is at rest in a constant external magnetic field...

The concept of virtual particles come from the mathematical structure of perturbation theory. Even more than that, they come from Feynman diagrams, which is a way to interpret the terms in the perturbation in field theory. This poses two points: 1) Although people interpret some phenomena...

Alright! So you were talking about a complex phase space. That's interesting! Regarding the similarity transformation I also buy the argument since the inner product is defined with respect to a pseudo-metric, which is not the usual case in quantum mechanics. This similarity transformation is...

It certainly is an extension but I don't think it's a simple extention to the complex domain. Quantum mechanics already deals with complex numbers so I don't know what you mean by 'an extention to the complex domain'. The PT-symmetric Hamiltonian cannot be mapped to a self-adjoint operator vie...

Physicists assume that observables are represented by self-adjoint ('Hermitian') operators because they guarantee that the corresponding eigenvalues will be always non-negative. The theory was aparently structured in this way because, I think, this might have been somewhat obvious for them at...
