Titolo

• Edge channel mixing induced by potential steps in an integer quantum Hall system (literal)

Abstract

• We investigate the coherent mixing of copropagating edge channels in a quantum Hall bar produced by step potentials. In the case of two edge channels it is found that, although a single step induces only a few percent mixing, a series of steps could yield 50% mixing. In addition, a strong mixing is found when the potential height of a single step allows a different number of edge channels on the two sides of the step. Charge density probability has been also calculated even for the case where the step is smoothened. (literal)
