Magnetic Fields Turn The Vacuum Into A Superconducting Superlens, Says Physicist� - Technology Review

Magnetic Fields Turn The Vacuum Into A Superconducting Superlens, Says Physicist� - Technology Review: Now Smolyaninov has turned his attention to the superconducting behaviour of the charged ρ mesons generated in a vacuum by a magnetic field. He points out that this superconducting state behaves exactly like a metamaterial, focusing light in exotic ways.

If this magnetic field varies in space in the right kind of way, it's quite possible for this superconducting state to focus light like a superlens. Equally it could also trap light like a black hole.
Nobody has created a magnetic field powerful enough to observe this effect on Earth but such fields must have existed elsewhere. Both Smolyaninov and Chernodub say that in the early Universe, just fractions of a second after the Big Bang, the fields must have been powerful enough to generate these superconducting states.
