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."

      Unfortunatly, they didn't select my submission, but the idea is basically unbound electrons have some quantum numbers related to spin and charge, but electrons bound to a nucleus have another quantum property related to the orbital they exist in (as a result of all those pesky electron orbital exclusion properties we get a taste of in chemistry 101). This gives the electron a sort of angular momentum quantum property (that is angular momentum isn't a continuous property, but is quantized to certain discrete values).

      You might imagine that in the classical sense, if you bumped an electron out of orbiting one nucleus and it be bound to the next nucleus in a lattice, the idea of what angular momentum all the electrons had would be somehow be conserved as a whole in the system on average. Now you toss in the fact that in a lattice, these otherwize local effects of virtually exchanging angular momentum might become delocalized from their actual particles and still maintain the required system average and also (in certain circumstance) still reveal their orignal quantum nature (instead of continuous approximation), that's the effect you have. It isn't a real particle exhibiting quantum effects, but a quasi-particle, but in some sense we've split-off the angular momentum effect from the actual electron that is bound (w/o unbinding the electron).

      If you are familiar with semiconductors, you can often hear of people talking about "holes" conducting electric charge like they are electrons, but they aren't electrons: it's a "hole" in a sea of delocalized electrons doing that charge transport. Usually the effects we are interested in are quite classical (say like average current), but in smaller dimensions and lower energy levels we start exhibiting quantum effects of these quasi-particles (say like in supercondutors).

      I don't know how this orbiton angular momentum thing will be useable. The effect that was observed was that excitation to higher orbits (higher angular momentums), can propagate in the lattice which seems less useful (eventually you are in such a high excitation energy, you are beyond most interesting quantum effects or effectively unbound). One speculation that I have is that certain insulator properties will be quantized (if certain orbits are unavailable, and the incoming quantum angular momentum is incompatible with the available orbits), and maybe that can be used for some storage capabiltiy or maybe somehow helping spintronics (which is sort of what these folks were thinking).

      It's the medium. When you look at a quasiparticle, it only exists in the context of its medium, whereas fundamental particles exist in the vacuum.

      Another example of quasi-particles are phonons. Maybe easier to understand. Phonon makes you think of sound (phonograph). What is sound? It's waves of compression of air molecules. Sound can travel through solids, too, in which case it's waves of compression of the molecules in the solid. Imagine you have a lattice (regular array) of molecules, like a solid crystal, and you tap it on one side. Where you tap, it will push the molecules closer to other molecules, and those will push away other molecules, which then get close to other molecules, which get pushed away, etc.. You can pretend the molecules are connected by springs. (If you take calculus through differential equations, you'll probably solve this kind of boundary-value problem.) So a wave travels through the solid.

      The cool thing, mathematically, is that these waves bounce around inside the "box" of the solid as if they were billiard balls (though usually I think the phonons pass through each other, which isn't how billiard balls are, but I mean they bounce off the "walls"). So you can effectively stop thinking of molecules jiggling on springs, and instead think of a kind of "gas" of phonons bouncing around in a box, as if the waves are really particles. That's why they are "quasi" particles. They're not real, but they behave like they are. And like another poster pointed out, how exactly do you define a "particle" anyway? :)

      Now where things get really cool is when you shine laser light on a crystal. What is laser light? Either you think of light as electromagnetic waves, or you think of it as particles called photons. (Photo makes you think of light, right? :) So you can think of laser light as a bunch of photons with pretty much all the same energy (plus or minus some relatively small margin; in real experiments you even pass laser light through filters to make the range of energy/wavelength/frequency even narrower). In a technique called Raman spectroscopy (among other techniques), you shine a laser on a crystal and observe the light that bounces back. What happens here? Imagine one of the photons of light going in. It has a certain energy. The photon goes into the crystal and bounces off a phonon (again, like billiard balls). The photon comes back out with more or less energy. Say that it comes out with less energy. Where did that energy go? It smacked into the phonon! So you can actually measure how a material likes to vibrate by looking at the light that bounces back. The peaks in that spectrum of light (measured relative to the energy of the laser) correspond to the phonons. You can even get information by looking at the height and width of the peaks.

      So I hope this gives a simpler example of a quasi-particle, and how it can be useful to think this way. The article is a bit misleading, referring to breaking apart an electron, as if it was just one electron. But really they mean a bunch of electrons, acting together in (as the article also said) a "one-dimensional chain of atoms". So very roughly, maybe you can imagine something like a phonon in a "lattice" of electrons.

    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.

    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.

    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.

    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.

    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.
