Universal modeling of weak antilocalization corrections in quasi-two-dimensional electron systems using predetermined return orbitals

摘要: We have developed a method to calculate the weak localization and antilocalization corrections based on real-space simulation, where we provide 147 885 predetermined return orbitals of quasi-two-dimensional electrons with up 5000 scattering events that are repeatedly used. Our model subsumes Golub [L. E. Golub, Phys. Rev. B 71, 235310 (2005)] when Rashba spin-orbit interaction (SOI) is assumed. computation very simple, fast, versatile, numerical results, obtained all at once, cover wide ranges magnetic field under various one-electron interactions ${H}^{\ensuremath{'}}$ exactly. Thus, it has straightforward extensibility incorporate other than SOI, such as linear cubic Dresselhaus SOIs, Zeeman effect, even relevant valley pseudo spin degrees freedom, which should unique tool study new classes materials like emerging 2D materials. Using our computation, also demonstrate robustness persistent helix state against SOI.
