Topological phase diagram of a three-terminal Josephson junction: From the conventional to the Majorana regime

Topological phase diagram of a three-terminal Josephson junction: From the conventional to the Majorana regime

We study the evolution of averaged transconductances in three-terminal Josephson junctions when the superconducting leads are led throughout a topological phase transition from an $s$-wave to a $p$-wave (Majorana) phase by an in-plane magnetic field ${B}_{x}$. We provide a complete description of this transition as a function of ${B}_{x}$ and …
