Physicists Detect Elusive Orbiton By "Splitting" Electron
ananyo writes "Condensed-matter physicists have managed to detect the third constituent of an electron — its 'orbiton'. Isolated electrons cannot be split into smaller components, earning them the designation of a fundamental particle. But in the 1980s, physicists predicted that electrons in a one-dimensional chain of atoms could be split into three quasiparticles: a 'holon' carrying the electron's charge, a 'spinon' carrying its spin and an 'orbiton' carrying its orbital location. In 1996, physicists split an electron into a holon and spinon. Now, van den Brink and his colleagues have broken an electron into an orbiton and a spinon (abstract). Orbitons could also aid the quest to build a quantum computer — one stumbling block has been that quantum effects are typically destroyed before calculations can be performed. But as orbital transitions are extremely fast, encoding information in orbitons could be one way to overcome that hurdle."
Let's face it... the particle physicists make all this stuff up. Somehow they figured out how to use particle colliders to synthesise crack cocaine, and ever since then the stuff they've been coming out with has been ever more fantastical.
Reading stuff like this makes me wish I'd taken more a lot more science in college, maybe went for an entirely different degree. Because honestly I've no idea what they are talking about. If anyone could possibly explain this a bit more I'd be really very happy.
Can someone actually explain this? I am trying to get my head around a one-dimensional anything ...
Wikipedia says this about Mott insulators: Mott insulators are a class of materials that should conduct electricity under conventional band theories, but are insulators when measured (particularly at low temperatures). This effect is due to electron-electron interactions which are not considered in conventional band theory.
I believe you're over-thinking the one-dimensional attribute. It simply means they're using a straight-line chain of the molecules in question. There are no molecules in the construct branching off at any other angle, that's all.
i have trouble understanding politicians too.
Maybe a flying car can be made feasible with a new kind of drive, like ejecting orbitons from the bottom.This research is in order to understand stuff. Forget about flying cars, maybe FTL drive is possible.
Think about the laser. When is was first conceived of by Einstein he had no way of doing it and no application for it. When Lamb and Retherford made it work there still was no use for it. But think about the world now: Internet, CD/DVD/Blu ray players and even the next gen IC fabs are based on the laser. Many metal parts are cut with lasers, welding is sometimes done with lasers (high presision work) and many measurements are done with lasers. If there had been no theoretical physics last century we wouldn't have lasers. Who knows what we could do with another century of theoretical research?
Well, I might have a way, but it only works on a semi spherical planet in a vacuum.
All I know I know is that they are NOT FUNNY.
All you have to do is just become a particle physicist yourself, discover a completely new set of even smaller particles and you can setup any IUPAC-like standardized naming convention you want for those. For the current particles, it's probably best to keep using the current standardized names.

It's not going to be FTL. FTL would leave the universe pretty crowded by now. Maybe it will allow exit from the conventional universe, that would explain Fermi's paradox.

It'd be less fun than you might think. In these post-9/11 days, do you think the government would actually let people fly their cars? No, even if the engineering problems were solved, the car's controls would only be accessible via an autopilot box fitted with more anti-tamper measures than an XBox 360 and embedded in a cube of epoxy. You'd only be able select from it's list of pre-approved 'safe landing zones' and it'd do the rest. The law will be proposed within a month after the first case of a drunk flier crashing into a building. Within a week if a child is killed.
There's a good one in a previous comment thread above here.
I think the 'heaviest' particle should be deemed the Megatron, in keeping with the WTFatron naming convention.

Leaving aside all the political gobbledygook, I'm totally in for an automated personal flying car.
..it is called a "holdon".
As in; hold on, we better check these results again.
There are not that many, and there isn't a good systematic way to name them anyway. The root of the word denotes the basic property that describes the particle.
'holon' comes from 'hole', which is the absence of a particle. that may sound weird, but in quantum mechanics, everything is discrete so a particle present or absent is like a binary 1 or 0, and the 0 states (holes) are just as good as 1 states (particles).
'spinon' comes from 'spin', which is the intrinsic angular momentum.
'orbiton' comes from 'orbital', which is the agular momentum from the orbital motition around the nuclei.
There are lots of other quasi-particles that occur in condensed matter, pasmons, phonons, polarons, polaritons, and so on. They all arise as emergent effects from interactions between large numbers of 'fundamental' particles, such as electrons.
Imagine a long chain of molecules, so that the electrons jump from orbiting one molecule to another along a 1D path.
A Mott Insulator is an insulator (ie it doesn't conduct electricity), but one that is caused by interactions between electrons. In an ordinary insulator (a 'band insulator') doesnt conduct electricity because there are simply no available orbital states for the electrons to move into. Imagine a series of boxes, with electrons as balls moving from one box to another. In a band insulator the boxes are full, so you simply can't move the balls around. In a Mott insulator however, the boxes are plenty big enough but the interactions between the electrons (balls) are strong enough that you can't put more than one ball in each box. So you end up with one ball per box and nothing can move.
It'd revolutionise transport, yes. A good thing, assuming it's no more energy-hungry than existing cars. But the dream of a flying car you can really fly, free to cruise the skies, to go wherever you please... out of the question.
Give a short, complete, accurate answer to this question: what is a particle?
If you must be ignorant, keep an open mind. Outside of the scale that human senses are designed to appreciate, extrapolation from experience tends not to be very useful.
Those who advocate genocide deserve every protection afforded by law, and none afforded by common human decency.

Charge-spin separation and spin-orbital separation are specifically effect of electron collective behavior in one-dimension: that is when the motion of electron is constrained to have one degree of freedom. Think of a single-lane road in which lane change is forbidden.
The only possible interpretation of any research whatever in the 'social sciences' is: some do, some don't
We need an IUPAC-like standardized naming convention for these particles
star trek?
are they the particles that enable you to light a fart on fire? i've only ever heard of that being possible when you're drunk
i think you're ejecting orbitons out of your bottom
(Honestly not the same AC): WTF is up with you mods? Snarxiv is hardly a troll website, and neither is pointing it out in this context. (Hint: It was made by a HEP theory researcher, poking a bit of fun at his own field -- it's the kind of thing Human Beings like to do sometimes...)
Only the likes of Sheldon Cooper with superior intellect to the others' may understand this.
and that is a good thing, think of how awful drivers are on a 2D surface
Snowden and Manning are heroes.
Physicists should use the D&D alignment and class system to assign particle names. Muon neutrino becomes neutral evil cleric, Up quark is lawful good fighter, etc.
I have unicorn ponies for sale. Males only, 9-12 hands in blue, pink and rainbow. Some have been ridden but most not. Horns are as-found. Pls reply at the usual email for the sale and delivery info.
ILL TAKE TWO!
If regular unicorns fart rainbows, do gay unicorn ponies fart plaid? Inquiring minds want to know!
Oh, I'm sorry sir, I thought you were referring to me, Mr. Wensleydale.

Bloody santorum, I would imagine... or am I being too literal here?
I can see the fnords!
damn, I got excited when I first misread that as Physicists detect elusive orbitron .

I can't watch the big bang theory. If Sheldon was so smart there is no way he could be a proponent of string theory.
Shouldn't they have renamed the electron the "hardon" because it is so difficult to split into smaller components?

They called the atom itself an "atom" because it was considered hard to split (from the Greek: a- = not; tom = split). Since the atom was split, two of the particles inside an atom was itself called the hadron, from the Greek word for "thick". The resemblance between "hadron" and a slang term for something else that gets "thick" led to all sorts of dick jokes in comments to news articles about the LHC.
The original names for quarks were based upon a poem by James Joyce. There are some other rather esoteric names that have come up in science over the years so such references really aren't totally unheard of.
I'm not sure about crack cocaine...but I've heard that they use these colliders to generate a significant amount of speed.
My God can beat up your God. Just kidding...don't take offense. I know there's no God.
It's certainly a possibility. The cost of killing most of the people on one planet is coming down a lot faster than the rate at which we are adding new planets to live on. We'll soon reach the point where a well funded terrorist could bring down an asteroid and wipe out western civilization (and most of the rest, but I think evidence suggests they'd consider that a victory scenario).
I'm sure there are other hazards ahead of us as well. But if there were some technology thing that would accidentally kill us all (rather than intentionally) it seems likely we'd be able to see that happening in the universe.

You have no clue what you are talking about, and you know it. for proof I present a post you made in this very thread:

YO seriously underestimate the size of the universe.
IF a civilization could travel at 100 time the speed of light, they would only scratch a tiny bit of the universe before that civilization died out.
Plus you assume that because someone else didn't discover something, that there is nothing to discover.
Which is an attitude parent have used to squash children dreams for generations.
The Kruger Dunning explains most post on
I think you're underestimating the size of the galaxy. At 100x the speed of light it takes only one advanced race to fill it up quite rapidly. And then the same goes for each other galaxy, plus you'd be seeing quite a few species make it to additional galaxies by now. A civilization doesn't have to last that long, just the technological capability of the species. A species only 10 times as mature as ours would have had plenty of time to reach additional galaxies by now, and there's plenty of room for species as much as 1000 times as mature.
"Who is the Journal of Quantum Physics going to believe?" --Stephen Hawking
On the other hand, there is a small, but measurable, chance that we're the most mature species in the galaxy. Maybe we're on track to fill it up while some other poor buggers are just now starting to make stone tools and we'll show up just as they start their first atomic bomb tests or something.
I mean, people look at it as some advanced civilization will come and wipe out our poor primitive selves, but someone had to be first, and maybe that's us. I mean, why not?
Sure, statistical chance is one possible explanation. Someone does have to be first. But to say that the chance is small is underselling it ... it is remotely tiny. The 'first' civilization should have been multiple billions of years ago. That we'd get this 'lucky' is so close to impossible that we have the whole 'Fermi paradox' name for it.
"Who is the Journal of Quantum Physics going to believe?" --Stephen Hawking
That's the whole question behind the fermi paradox. If pWe_Are_First should be small, yet we seem to be first, are we wrong about the probability, about the being first, or are we incomprehensibly lucky?
"Who is the Journal of Quantum Physics going to believe?" --Stephen Hawking
And understanding the difference is a hairy problem.
I would have given you points for this if you hadn't posted AC ;)
Thanks.

This sig is not paradoxical or ironic.
When I saw "orbiton" the first thing that popped into my mind was "armitron". I have one stuck in a closet somewhere.
