用Hartree-Fock近似研究了周期势对高Landau能级实现的条纹相的影响。电势的周期被选择为条纹相的基本周期的两到六倍。结果发现，与天真的预期和流体力学理论相反，该条纹垂直于外势排列。对于目前意想不到的新结果的发生，沿条纹的维格纳结晶的电荷调制是必不可少的。
The effect of periodic potential on the stripe phase realized at high Landau levels is investigated by the Hartree–Fock approximation. The period of the potential is chosen to be two to six times the fundamental period of the stripe phase. It is found that the stripe aligns perpendicularly to the external potential in contrast to a naive expectation and hydrodynamic theory. Charge modulation towards the Wigner crystallization along the stripe is essential for the occurrence of the present unexpected new result.
