In my spare time, I have often thought about powering my Marshall stack with a hydrogen bomb, but it seems I’ve been beaten to it by Andrew Murray, a physicist at the University of Manchester, UK., who has found a way to trap atoms using his old amps! Now, while this has obvious applications for stadium rock pyrotechnics shows, it may also help in the development of quantum computers. Previously scientists used a complex system of lasers and force fields (much like an Iron Maiden concert) in order to trap super-cooled atoms so they can be examined – very useful if you’re into your physics, but hard to do, and not terribly accurate. The solution? Use an old amp speaker instead! According to Murray:
“The alternating [magnetic] field can be used to trap atoms as long as we ensure that the laser beams change polarisation along with it,” says Murray. “We can switch the fields off about 300 to 500 times faster [than before].” That’s fast enough to ensure that the atoms have not had time to escape the trap when they are zapped with an electron beam.
Basically producing an instant, accurate atom-trap! Good news for physicists, and if can be adapted to hold punters still, then great news the next time I play a gig and the audience tries to leave!
