Matterwave's latest activity

Yeah, I think in general you need some vector field to "ground" you as you move around the manifold. In my post #3 I suggested using a...

Yes, but that choice is path dependent. Any two tangent spaces at ##p_1,\, p_2## can be made isomorphic via the connection if you...

This paper by Zurek may be a better reference. He discusses orthogonal microstates, https://doi.org/10.1103/PhysRevA.71.052105

Would you let me know where you saw this trick? Is it from the paper jbergman posted?

Not having read past eqn. 10, it really does seem to me like this paper is at least trying to resolve @Roberto Pavani concerns. Eqn 10...

While in general this is a caveat that needs to be kept in mind, for the particular case under discussion here, spin measurements on...

Branch number is not uniquely defined by decoherence. Decoherence yields an approximate branch structure, not a count of observers or...

Ah got it, I was not familiar with this terminology. Hadn't realized this. Interesting point. Given the basis exists on ##D##, how...

Can you define what it means for a neighborhood to be parallelizable?

Are you referring to this documentary?

I agree with @PeterDonis that this is a major open issue in MWI. Here is my understanding, which could be quite flawed, and I'd love...

It seems this paper is exactly what @Roberto Pavani asked for -- a publish paper which uses the square root of the full contraction of...

Agree. My statement was sloppy.

More precisely, you don't interpret it as an actual process, but as an artifact of branching. See below. No, you can't do that, because...

There's a degree of flexibility in how you define distance in a non-stationary spacetime like those containing gravitational waves. You...
