Transport probe of nonadiabatic transition caused by Majorana moving

We propose a transport probe scheme to detect the nonadiabatic transition caused by Majornana moving, which is relevant to the braiding operations in topological quantum computation. The scheme is largely based on a time dependent single-electron-wavefunction approach to quantum transport. Applying the Kitaev model, we simulate the time dependent Andreev-reflection current and examine the feasibility of using the current to infer the nonadiabatic transition. We design a scheme to determine the Landau-Zener tunneling ratio in the context of transport, and compare it with the result obtained from the isolated quantum wire. Desirable agreements are demonstrated for the proposed scheme.
