Lateral confinement in LAO/STO nanowires reverses the t2g orbital energy ordering, and topological superconducting phases appear preferentially when the heavy, nearly flat yz bands begin to fill.
For the chemical potential µ14C close to 0 meV, the highest subbands shown in the lower panel of Fig

Evolution of topological superconductivity by orbital selective confinement in oxide nanowires
Lateral confinement in LAO/STO nanowires reverses the t2g orbital energy ordering, and topological superconducting phases appear preferentially when the heavy, nearly flat yz bands begin to fill.
