Query: Manipulation and Characterization of the Valley Polarized Topological
  Kink States in Graphene Based Interferometers   Valley polarized topological kink states, existing broadly in the domain wall
of hexagonal lattices systems, are identified in experiments, unfortunately,
only very limited physical properties being given. Using an Aharanov-Bohm
interferometer composed of domain walls in graphene systems, we study the
periodical modulation of pure valley current in a large range by tuning the
magnetic field or the Fermi level. For monolayer graphene device, there exists
one topological kink state, and the oscillation of transmission coefficients
have single period. The $\pi$ Berry phase and the linear dispersion relation of
kink states can be extracted from the transmission data. For bilayer graphene
device, there are two topological kink states with two oscillation periods. Our
proposal provides an experimental feasible route to manipulate and characterize
the valley polarized topological kink states in classical wave and electronic
graphene-type crystalline systems.
