When an exciton acts like a hole

(Phys.org) —When is an electron hole like a quasiparticle (QP)? More specifically, what happens when a single electron hole is doped into a two-dimensional quantum antiferromagnet? Quasiparticle phenomena in such a system ...

Researchers create working Mott transistor prototype

(Phys.org) -- Engineers from several research organizations working together in Japan have developed a working prototype of a Mott transistor, a possible alternative to the standard silicon based field-effect transistor (FET). ...

Light pulses provide a new route to enhance superconductivity

Under normal electron band theory, Mott insulators ought to conduct electricity, but they do not due to interactions among their electrons. But now, scientists from the RIKEN Cluster for Pioneering Research have shown that ...
