Topological superconductivity in planar Josephson junctions: Narrowing down to the nanowire limit
We theoretically study topological planar Josephson junctions (JJs) formed from spin-orbit-coupled two-dimensional electron gases (2DEGs) proximitized by two superconductors and subjected to an in-plane magnetic field ${B}_{\ensuremath{\parallel}}$. Compared to previous studies of topological superconductivity in these junctions, here we consider the case where the superconducting leads are narrower than the …
