Summary: | Phys. Rev. B 94, 180505 (2016) We demonstrate theoretically that proximity-induced superconductivity in
silicene offers the possibility to exert strong quantum ground state control.
We show that electrically controlled $0$-$\pi$ transitions occur in Josephson
junctions in the presence of an exchange field due to the buckling of the
silicene lattice. We also discover that zigzag-oriented interfaces, featuring
intervalley scattering, cause a $\varphi_0$ state with an applied electric
field. Finally, we demonstrate that Majorana bound states along the silicene
edge are tunable via the edge orientation, electric, and in-plane spin exchange
fields. |
