Renormalization effects in spin-polarized metallic wires proximitized by a superconductor: A scattering approach

Thomas Kiendl, Felix von Oppen, Piet W. Brouwer

Spin-polarized normal-metal wires coupled to a superconductor can host Majorana states at their ends. These decay into the bulk and are protected by a minigap in the spectrum. Prev…
