2 Investigate orbital magnetic moment, valley Hall effects, and valley dependent optical circular dichroism; investigate excitons and the Berry phase effect on its transport; investigate charging effects of excitons; investigate the physics at the edge of the monolayers. 3 Investigate the interplay between spin and valley degrees of freedom; develop schemes for manipulating valley and spin dynamics by external controls in the bulk and on the edges; explore potential applications exploiting valley index as an information carrier.
