The role of the strain induced population imbalance in Valley polarization of graphene: Berry curvature perspective
Real magnetic and lattice deformation gauge fields have been investigated in honeycomb lattice of graphene. The coexistence of these two gauges will induce a gap difference between two valley points (K and K′) of system. This gap difference allows us to study the possible topological valley Hall cur...
