Reply to ‘‘Comment on ‘Existence of Wannier-Stark localization’ ’’

Abstract

As Kleinman claims in the preceding Comment, our work indicates that the staircase potential mixes Bloch states of different energy bands. However, Wannier-Stark states are superpositions of Bloch states. There is no contradiction with the argument of our work that coherence effects result in each electric-field-dependent energy band forming its own set of Wannier-Stark states.
