Researchers Working On Crystallizing Light 129

Posted by samzenpus from the tripping-on-the-light-fantastic dept.
An anonymous reader writes Researchers at Princeton University have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter. The researchers are not shining light through crystal – they are transforming light into crystal. As part of an effort to develop exotic materials such as room-temperature superconductors, the researchers have locked together photons, the basic element of light, so that they become fixed in place. "It's something that we have never seen before," said Andrew Houck, one of the researchers. "This is a new behavior for light."

      The British already did this in 1854 [wikipedia.org] - duh. There were even poems [wikipedia.org] about it.

    • My best guess would be yes you could use it as a battery and it would almost certainly be weaponized. As for how much energy could be stored my guess would be it would be the Planck Energy [wikipedia.org] * (1cm^3 / Planck Volume [wikipedia.org]) and I don't really feel like doing that calculation but it looks like it would be a lot given that the Planck Energy is about equal to the energy in an average car's tank of fuel and the Planck Volume is really small ~4^-104 m^3.

    • Except that in NextGen Star Trek (24th century and later), the holodeck uses photons restrained by force fields, totally different technology than what they're experimenting with here (I think).

        • Ok... Just for Hypothetical plausibility: They don't. The photons restrained by force fields create the matter from "nothing". Unrestrained photons that bounce off the restrained ones are what make it to someone's eye to give the person the vision of the environment simulated around them. Again, not saying this is the official explanation... just a plausible one.
        • Maybe it's the photons that bounce off the photons that you see? And maybe the force-field is there to stop those photons getting knocked out of place by every stray photon? Or maybe the Star Trek series is just cheap pulp that doesn't deserve the huge cult-like following it has....

They're probably generated separately and synchronized for realism. They never really explain in detail how holographic projections work in Star Trek, other than "photons and force fields" and "holoprojectors", which have a limited range and need to be placed strategically (the strategy isn't explained, either).

      From the article:

      To build their machine, the researchers created a structure made of superconducting materials that contains 100 billion atoms engineered to act as a single “artificial atom.” They placed the artificial atom close to a superconducting wire containing photons. By the rules of quantum mechanics, the photons on the wire inherit some of the properties of the artificial atom – in a sense linking them.

      They use a lot of "artificially" in the article. And I like the big jump of "By the rules of quantum mechanics".

    If you read the article, the scientists are not converting energy into matter.

    Instead, they have caused some photons to be entangled so that they gain some of the properties of "liquid or solids". Not all the properties, not even the properties of a crystal, instead some of the properties of 'liquid or solid"

    This article is just about one of the worst dumming down of science I have read. It was built up to sound 'click worthy', mainly be ignoring the actual research. They don't even use the word "entangled".

        We can define a photon just fine thank you. It's not because it doesn't fit in a human-scale model of comprehension that there's something inherently fuzzy or mysterious about the wave/particle duality. A photon is both a wave and a particle, exhibiting the properties of the former in certain scenarii and the latter in other scenarii.

        Your analogy is also incorrect. A photon is an electromagnetic wave, it's not a vibration propagating through a medium. An ocean wave without the ocean is nothing, it's energ

        • Actually, what I found intriguing about the article is that photons' "physical" properties appear to be relational, which goes a long way to explaining how they can behave as waves AND particles. It kind of seems like photons are really the relationship between the physical universe and the Higgs field, and are very much quantum. As such, photons are trainable based on what they interact with, and how they are measured. This has interesting ramifications for future modeling and even future means of photo

            Quantum mechanics has explained how photons act like waves and particles for nearly hundred years now. Wave functions explain photons just fine in such situations covering both when it acts like particles and when it acts like waves. In some cases you can make simplifications to the equations and get stuff that looks like classical particle behavior, and otherwise you get wave behavior, but it is still one underlying theory and model. It is no different than how Einstein's relativities can give you Newto

      This has been in the news a while back, and was dubbed "photonic crystals" then too (but that term was already in use for something completely different).

      Basically, you start with a quantum mechanical system (usually a bunch of atoms) that has very few degrees of freedom (some kind of potential trap). This is the "crystal" part.

      Then you add a number of photons to that system. The photons couple with the electrons in the lattice. Because of the restricted degrees of freedom, only very few

      In fairness to the writer of the simply hideous article, which is an amazing compendium of misleading nonsense, irrelevancy and outright falsehood, the research team seem to be speaking in a private language. Even their "popular summary" is difficult for a physicist who has done some work in quantum fundamentals to understand.

      It appears they have created a fairly standard state in which microwave photons are strongly interacting with each other via a superconductor. Their is for some reason they do not explain and seem to take for granted, a phase transition in the system's behaviour as the number of photons drops.

      This may (or may not) be related to the "phase/photon-number uncertainty principle", which is analogous to the usual position/momentum uncertainty principle: you can know the precise classical phase of a many-photon beam or you can know the number of photons in it, but not both at the same time. As the total number of photons goes down the uncertainty in the the number of photons goes down, increasing the uncertainty in the phase (that's one fairly hand-waving way to think about it, at least.)

      After the phase transition the system is in some weird quantum state that they liken to Schrodinger's cat, but since Schrodinger's cat is in a perfectly ordinary quantum superposition that knowledge adds exactly nothing to our understanding of what the state actually is. Presumably they are referring to some particular state that is currently well-known within quantum information theory, but by presenting the idea to a lay audience without elaboration they simply add to the overall sense of confusion and, uh, incoherence.
