Ultrafast all-optical generation of pure spin and valley currents

Abstract Pure currents comprise the flow of a two state quantum freedom – for example the electron spin – in the absence of charge flow. Radically different from the charge currents that underpin present day electronics, in two dimensional materials possessing additional two state freedoms such as v...
