@article{Zyuzin2015JosephsonJT, title={Josephson junction through a disordered topological insulator with helical magnetization}, author={Alexander A. Zyuzin and Mohammad Alidoust and Daniel Loss}, journal={Physical Review B}, year={2015}, volume={93}, pages={214502} }

We study supercurrent and proximity vortices in a Josephson junction made of disordered surface states of a three-dimensional topological insulator with a proximity induced in-plane helical magnetization. In a regime where the rotation period of helical magnetization is larger than the junction width, we find supercurrent 0 - pi crossovers as a function of junction thickness, magnetization strength, and parameters inherent to the helical modulation and surface states. The supercurrent reversals…
