Swimming upstream: Flux flow reverses for lattice bosons in a magnetic field

(Âé¶¹ÒùÔºOrg.com) -- Matter in the subatomic realm is, well, a different matter. In the case of strongly correlated phases of matter, one of the most surprising findings has to do with a phenomenon known as the Hall response ...

Âé¶¹ÒùÔºicists investigate electron fractionalization into not two, but three components

One of the many intriguing puzzles in physics is the strange behavior of the electron as it fractionalizes into two separate quasiparticles. These quasiparticles, called spinons and chargons (or holons), carry the electron’s ...
