Tuning Valley Polarization in a WSe_{2} Monolayer with a Tiny Magnetic Field
In monolayers of semiconducting transition metal dichalcogenides, the light helicity (σ^{+} or σ^{-}) is locked to the valley degree of freedom, leading to the possibility of optical initialization of distinct valley populations. However, an extremely rapid valley pseudospin relaxation (at the time...
