PopSci: For the First Time, Electrons are Observed Splitting into Smaller Quasi-Particles 1

We generally think of electrons as fundamental building blocks of atoms, elementary subatomic particles with no smaller components to speak of. But according to Swiss and German researchers reporting in Nature this week, we are wrong to think so. For the first time, the researchers have recorded an observation of an electron splitting into two different quasi-particles, each taking different characteristics of the original electron with it. Using samples of the copper-oxide compound Sr2CuO3, the researchers lifted some of the electrons belonging to the copper atoms out of their orbits and placed them into higher orbits by manipulating them with X-rays. Upon placing them in these higher--and higher-velocity--orbits, the electrons split into two parts, one called a spinon that carried the electron’s spin with it, and another called an obitron that carried the electron’s orbital momentum with it. Science, Clay Dillow, electrons, energy, particle physics, quantum physics, subatomic particles, superconductivitySpin and orbit are--at least as our basic understanding goes--attached to each particular electron. So the fact that they have been separated is pretty significant. And while researchers have thought for a while that this kind of separation could be theoretically achieved, they’ve had a hard time proving it empirically until now. It’s a reminder that at the quantum level there are still things that more or less mystify us.
But that’s not all it is. This particular observation of an electron splitting could have big-time implications in the field of high-temperature superconductivity. Understanding the way electrons can decay into quasi-particles could improve our overall understanding of the electron and how it moves, and thus help us figure out new ways of moving electrons--or electricity--around in bulk without losing large amounts of it as waste

So the electron splits into the spinon and orbitron, both move to the next orbit, then recombine into an electron?

physorg > everything else
This is cool, but me thinks the pub isn't ganna pay much attention to it. Even if it does lead to inexpensive lossless power distribution...
Wait what? yeah that.
Anyway, science and tech forums would give you interested responses. I've found they really like their science and tech, and not so much heady ass high talk though.
That ended up a lot longer then the originally planed physorg > everything. Oh shit, that just made it even longer! Ohh god a loop!!! 
EDIT: This made me LoL. For real, it did. The "post how dumb Americans are" thread is pwning this. Terrific aint it?

i dunno anything about the science behind quantum physics, but this simpsons intro is a pretty good representation of why i think we will never discover the smallest particles of matter (or how big the universe really is). Perhaps life is just a giant fractal and perhaps those tiny atoms and electrons are really just other universes or solar systems beyond the realm of human perception. We can manipulate them within our perception for our purposes, but do we really know how deep that rabbit hole goes? I'm not so sure.

Post the real abstract you drain bamaged bum 
Quote:
When viewed as an elementary particle, the electron has spin and charge. When binding to the atomic nucleus, it also acquires an angular momentum quantum number corresponding to the quantized atomic orbital it occupies. Even if electrons in solids form bands and delocalize from the nuclei, in Mott insulators they retain their three fundamental quantum numbers: spin, charge and orbital1. The hallmark of one-dimensional physics is a breaking up of the elementary electron into its separate degrees of freedom2. The separation of the electron into independent quasi-particles that carry either spin (spinons) or charge (holons) was first observed fifteen years ago3. Here we report observation of the separation of the orbital degree of freedom (orbiton) using resonant inelastic X-ray scattering on the one-dimensional Mott insulator Sr2CuO3. We resolve an orbiton separating itself from spinons and propagating through the lattice as a distinct quasi-particle with a substantial dispersion in energy over momentum, of about 0.2 electronvolts, over nearly one Brillouin zone.

I find it really interesting. But I have no competence whatsoever to understand what it means and how significant it can be.
I just glad they discovered it.

If we can find out how and why electrons do this someday we might be able to combine large quantities of quasi electron particles in small packages and transmit them great distances before re assembling the electrons. There could possibly be the ability create a whole new field of designer atoms.

Custom built atoms. It would be pretty cool.
All we would have to do after that is make sure these new atoms are stable and not radioactive.
