Quantum analog of channeled electron trajectories in periodic magnetic and electric fields

摘要

We calculate the quantum states corresponding to the drifting and channeledclassical orbits in a two-dimensional electron gas (2DEG) with strong magneticand electric modulations along one spatial direction, $x$. The channeled statescarry high, concentrated currents along the $y$ axis, and are confined in aneffective potential well. The quantum and the classical states are compared.
