摘要：
We propose that the transport anisotropy observed in half-filled high Landau levels (N >= 2) is caused by the space noncommutativity effect, namely the Heisenberg uncertainty relation between the spatial coordinates of electrons. We make a renormalization group analysis and find that the noncommutativity effect is able to drive the stripe formation only at half-fillings nu = 9/2, 11/2, 13/2, etc., in agreement with experiments.
