Getting Back Mojo…

Topics: Applied Physics, Lasers, Magnetism, Materials Science, Phonons When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10–15 seconds). The spin, or angular momentum, of the electrons in the material, thus disappears almost instantly. Yet all that angular momentum cannot simply be lost. It must be conservedContinue reading “Getting Back Mojo…”

Virgin Hyperloop…

Topics: Economics, Futurism, Magnetism, Transportation In the desert just north of Las Vegas, a long white metal tube sits at the base of the mountains, promising to one day revolutionize travel. That is where Virgin Hyperloop, whose partners include Richard Branson’s Virgin Group, is developing the technology for passenger pods that will hurtle at speedsContinue reading “Virgin Hyperloop…”

Kondo Mimic…

Topics: Magnetism, Materials Science, Nanotechnology A new type of quasiparticle – dubbed the “spinaron” by the scientists who discovered it – could be responsible for a magnetic phenomenon that is usually attributed to the Kondo effect. The research, which was carried out by Samir Lounis and colleagues at Germany’s Forschungszentrum Jülich, casts doubt on current theories of theContinue reading “Kondo Mimic…”
