中文摘要	we theoretically investigate the charge transport in the quantum waveguides in the presence of the rashba spin-orbit interaction and the dresselhaus spin-orbit interaction. we find that the interplay between the rashba spin-orbit interaction and dresselhaus spin-orbit interaction can induce a symmetry breaking and consequently leads to the anisotropic charge transport in the quantum waveguides, the conductance through the quantum waveguides depends sensitively on the crystallographic orientations of the quantum waveguides. the anisotropy of the charge transport can even survive in the presence of disorder effect in realistic systems.
