Hello!
I am studying particle physics. While reading the papers I realized that many authors of papers regarding the search for Odderon refer to "forward-backward assymetry", "charge assymetry". However, all my attepms to find a good description and definition of mentioned assymetries failed...
well, probably black hole can create a new universe. i just never saw the solution for such scenario.
i just suggested a model where we have only a few electrons in the universe.
Let's make the question simpler: when we measure the momentum of particle by momentum operator, what is the...

Right now QM is more describing than explaining. Actually its authors never put the goal to explain why it happens, instead they just tried to make predictions what would happen in the experiment. And this is normal. Newton first make mathematical model for gravity, but...
Doing some kinematical calculations we say that particle possesses momentum p. It is definite, so we choose momentum representation to describe the state of particle. However I am curious in what frame of reference we measure particle momentum.
We can not assign frame of reference to any...
Hi! I encountered the problem that I need to decompose the Green function into a set of eigenfunction. Particularly, I have the free space Green function
G(\vec r; \vec r') = \frac {e^{i k | \vec r - \vec r'|} } {4 \pi | \vec r - \vec r'|}
and I need to express it into series of...
nothing keeps electrons from falling onto protons. in fact if we consider the atom of hydrogen, electron does not even move around the protons (orbital momentum is zero for ground state, l=0). Only uncertainty principle prevents matter from collapse to a point.
Virtual photons in fact are just...
I am graduate student working now at the project in cosmology. I would appreciate any links or references to the papers or publications casting a light on the problem of accelerated expansion of the universe.
Did they found the rate of accelerated expansion?
