Effective theory approach to the Schrödinger-Poisson problem in semiconductor Majorana devices
We propose a method for solving the Schr\"odinger-Poisson problem that can be efficiently implemented in realistic 3D tight-binding models of semiconductor-based Majorana devices. The method is based on two key ideas. (i) For a given geometry, the Poisson problem is only solved once (for each local orbital) and the results …
