Pitt Researchers Create New Form of Matter
University of Pittsburgh ^ | May 17, 2007 | Morgan Kelly

Posted on 05/20/2007 9:09:29 PM PDT by SunkenCiv

The new state is a solid filled with a collection of energy particles known as polaritons that have been trapped and slowed, explained lead investigator David Snoke, an associate professor in the physics and astronomy department in Pitt's School of Arts and Sciences. Snoke worked with Pitt graduate students Ryan Balili and Vincent Hartwell on the project. Using specially designed optical structures with nanometer-thick layers-which allow polaritons to move freely inside the solid-Snoke and his colleagues captured the polaritons in the form of a superfluid. In superfluids and in their solid counterparts, superconductors, matter consolidates to act as a single energy wave rather than as individual particles. In superconductors, this allows for the perfect flow of electricity. In the new state of matter demonstrated at Pitt-which can be called a polariton superfluid-the wave behavior leads to a pure light beam similar to that from a laser but is much more energy efficient. Traditional superfluids and superconductors require extremely low temperatures, approximately negative 280 and negative 450 degrees Fahrenheit for a superconductor and superfluid, respectively. The polariton superfluid is more stable at higher temperatures, and may be capable of being demonstrated at room temperature in the near future.

Very cool. Bump for later reading.

PING TO timer . . .

sounds like your stuff.

Yeah, did not our lord ask : does your heart leap for joy upon hearing the truth? Instead it seems I’ve been spreading seeds all over the hard, asphalt road...no fertile soil here...where might it be?

LOL.

Heading to bed. Hope your hot tub is coming along well.

Prayers for mom still . . . no other results from my efforts.

Sigh.

Hmmm, wonder if this development could bypass the synchrotron in the SFC/RIS garbage to pure isotopes process. Is this lasar light tuneable to various frquencies? SFC = Synchrotron/Fiber optics/Capacitor. RIS = Resonant Ionization Spectroscopy.

This sort of thing fascinates me.

Unlike most Hollyweird pretty boys, he can act. Or at least, he could when he wasn’t just a punchline in a joke starring Anjelina Jolie.

There is at least one tuneable laser (I’m not current, as it were, on lasers), but I don’t think laser efficiency is adequate for the task you suggest.

Yes, lasars are only about 1% efficient. The free electron lasar is in use in Idaho but again, you have to go for rare and expensive isotopes to make it worth the energy input. They also use it to remove radioactive isotopes(remediate nuclear waste)but LENR is far better at that. But there too many yucca mountain financial toes are stepped on and dingy harry(D-NV)wouldn’t lift a finger there to help, too much federal patronage involved.

The spectrum-spray from a synchrotron would be more viable : thru sapphire windows/fiber optics cables/to capacitor grids where individual species of isotopes are ionized/bond w/the substrate(in a large helium-flow pipe).

This polariton process supposedly produces lasar light more efficiently, could it be tuneable to operate the RIS process so as to turn garbage, even nuc-rad-waste, into pure isotopes? If so, land fills become gold mines....
