Tel Aviv University's astounding "quantum levitation" demonstration
By Bridget Borgobello
20:39 October 23, 2011
(...)Lead by Prof. Guy Deutscher, the Tel Aviv University team has been experimenting with superconductors to produce "quantum trapping" and "quantum levitation" shown in the ATSC video below.

The experiment uses a crystal sapphire wafer 500 microns wide coated in a yttrium barium copper oxide (YBCO) ceramic. This "puck" is then cooled below -185ºC (-301ºF) using liquid nitrogen at which point it becomes a superconductor, meaning it's able to conduct electricity without energy loss or resistance. (...)

That's awesome. Edited by michel123456

Didn't watch the video clip, but was rhis 'hi-temp" superconductor levitated by a magnet ?

 

One property of superconductors is their ability to expel magnetic fields resulting in 'levitation'.

This is one property spurring research to find room temp superconductors. Of course a viable theory of superconductivity would be a great help.

What's actually going on? You have this thing called a gauge boson which carries the EM force made of energy, and then it pretty much follows a straight path...is there more than one type of it?
