A novel universal light-based technique to control valley polarization in bulk materials

"main aim of valleytronics to reach the valley polarization in materials, without being restricted by specific chosen material, enabling creation of classical and quantum gates and bits, furthering low-energy consumption, efficient, fast switching information storage... initial measurement was tried on bulk MoS2, saw valley polarization signature... trefoil field, whose symmetry matched triangular sub-lattices constituting hetero-atomic hexagonal materials... rotating incident light field modulated valley polarization"
