磁场中的布洛赫电子--为什么混沌以艰难的方式发送电子？
Bloch Electrons in a Magnetic Field - Why Does Chaos Send Electrons the Hard Way?
摘要：
我们发现，在x和y方向上具有不同调制幅度的二维周期势和垂直的磁场可能导致沿较强调制方向的电子输运和沿较弱调制方向的局域化的转变。在实验可访问的制度，我们将这种新的量子传输现象，以避免由于经典混沌带交叉。
英文摘要：
We find that a 2D periodic potential with different modulation amplitudes in x- and y-direction and a perpendicular magnetic field may lead to a transition to electron transport along the direction of stronger modulation and to localization in the direction of weaker modulation. In the experimentally accessible regime we relate this new quantum transport phenomenon to avoided band crossing due to classical chaos.
