bhobba reacted to PeterDonis's post in the thread Graduate Quantum interpretations and indistinguishable elementary particles with
Like.
"Cannot label them" is too strong a statement. If I have a single electron captured in a Penning trap, I can label it as "the electron... -
bhobba replied to the thread High School Question about the spatial extent of a single photon in entanglement.What we deal with in ordinary non-relativistic QM is a very good approximation to the non-relativistic limit of Quantum Field Theory...

bhobba reacted to Nugatory's post in the thread High School Question about the spatial extent of a single photon in entanglement with Like.
Of course, and that's always been how we view it: the entangled pair is not two distinct particles, it is a single quantum system...

bhobba reacted to Demystifier's post in the thread High School Seemingly odd quantum tunneling with Like.
A good example is a neutron. A free neutron is unstable, it decays, but a neutron in an atomic nucleus is stable.

bhobba reacted to Cthugha's post in the thread High School Seemingly odd quantum tunneling with Like.
In a nutshell, that is alpha decay.

bhobba reacted to PeterDonis's post in the thread High School Seemingly odd quantum tunneling with Like.
If the scenario is such that you can consider the molecule as a "particle", it has some nonzero probability to tunnel through a barrier...
-
bhobba reacted to PeterDonis's post in the thread High School Seemingly odd quantum tunneling with Like.
Because if the particles are bound inside a large object, they're not free particles, and all the stuff you refer to about tunneling and...

bhobba reacted to .Scott's post in the thread Graduate Quantum interpretations and indistinguishable elementary particles with Like.
Not "wave", "wave function". It provides the weighted distribution of all the places where you might find a particle. When used that...

bhobba reacted to PeterDonis's post in the thread Graduate Quantum interpretations and indistinguishable elementary particles with Like.
To clarify a point that might be confusing here, in the light of what I said in post #8 earlier in this thread: if I have a single...

bhobba reacted to PeterDonis's post in the thread Graduate Quantum interpretations and indistinguishable elementary particles with Like.
You still don't appear to grasp that "an individual physical system" in QM is not the same thing as an individual elementary particle...

bhobba reacted to PeterDonis's post in the thread Graduate Quantum interpretations and indistinguishable elementary particles with Like.
Yes. Nobody is disputing that. But, as I've already pointed out, this fact has nothing to do with ensemble interpretations vs...

bhobba reacted to Lord Jestocost's post in the thread Graduate Quantum interpretations and indistinguishable elementary particles with Like.
As far as the term “identical particles” is concerned, there is probably no need for any interpretation-related issues in physics...
-
bhobba replied to the thread Graduate Quantum interpretations and indistinguishable elementary particles.It's trivial in QFT. Ordinary QM is only an approximation to the relativistic limit of QFT. There are no antiparticles in ordinary...

Love.
I've read Misner, Thorne, & Wheeler in full, more than once, as well. Which took, um, quite a bit longer than it took to read... -
