I was reading about this latest announcement - a research group has used a laser to create polaritonic vortices: http://www.laboratoryequipment.com/news/2014/11/laser-creates-quantum-whirlpool What can this type of technology lead to? What could it allow us to do? The article mentions that such polaritonic vortices could be used to detect minute electromagnetic fields, like what a SQUID can do. Could this lead to the Star Trek style of remote sensing, whereby even small electromagnetic fields could be detected at a distance? Or will this type of approach always be confined to laboratory instrument devices? Furthermore, could it be used to enhance things like Molecular Beam Epitaxy or Laser Chemical Vapor Deposition?
