Landau-Zener transitions in a linear chain
arXiv:cond-mat/0112419 · doi:10.1103/PhysRevB.65.153105
Abstract
We present an exact asymptotic solution for electron transition amplitudes in an infinite linear chain driven by an external homogeneous time-dependent electric field. This solution extends the Landau-Zener theory for the case of infinite number of states in discrete spectrum. In addition to transition amplitudes we calculate an effective diffusion constant.
