Skeptical.
If a negative energy appears somewhere, it is always an indication of a direction problem, or in other words a geometric problem, which... -

The following is taken from Bjorken and Drell, Relativistic Quantum Mechanics (1964), pp. 5-6: So the problem with the Klein-Gordon... -

If doesn't work in relativistic context. For example, if you apply it to Klein-Gordon equation then probability is not conserved.

The main problem is how to define probability density for particle positions. QFT avoids that problem by saying that the theory at the...

Hi All While going through my book on QFT for mathematicians (What Is a Quantum Field Theory? by Michel Talagrand) I came across the...

No.

I guess there are not too many things to do with them. You could analyse their position-momentum uncertainty, you could analyse the 2D...

In the link, the part in bold above refers to functions from the Schwartz space. The Schwartz space is the function space of all...

Sure you have, just not under that name. The Hermite functions are Gaussians with polynomial prefactors--indeed, the zero-order Hermite...

yes, and a very poor one in most cases, except when a system is nearly in the ground state (as for molecules in much of quantum...

This is basically what you're asking: https://arxiv.org/pdf/cond-mat/0101157 A global momentum measurement of the screen only yields...
