Bidirectional flow of two-dimensional dusty plasma under asymmetric periodic substrates driven by unbiased external excitations
Collective transport properties of a one-dimensional (1D) asymmetric periodic substrate modulated two-dimensional (2D) dusty plasma g5210t-p90 driven by an unbiased sinusoidal excitation force are investigated using Langevin dynamical simulations.It is discovered that by changing the amplitude and frequency of the unbiased sinusoidal external excit
