Query: Spin-orbit coupling induced valley Hall effects in transition-metal
  dichalcogenides   In transition-metal dichalcogenides, electrons in the K-valleys can
experience both Ising and Rashba spin-orbit couplings. In this work, we show
that the coexistence of Ising and Rashba spin-orbit couplings leads to a
special type of valley Hall effect, which we call spin-orbit coupling induced
valley Hall effect. Importantly, near the conduction band edge, the
valley-dependent Berry curvatures generated by spin-orbit couplings are highly
tunable by external gates and dominate over the intrinsic Berry curvatures
originating from orbital degrees of freedom under accessible experimental
conditions. We show that the spin-orbit coupling induced valley Hall effect is
manifested in the gate dependence of the valley Hall conductivity, which can be
detected by Kerr effect experiments.
