Topological insulator (TI) nanowires in proximity with conventional superconductors have been proposed as a tunable platform to realize topological superconductivity and Majorana zero modes (MZM). The tuning is done using an axial magnetic flux $\Phi$ which allows transforming the system from trivial at $\Phi=0$ to topologically nontrivial when half a magnetic flux quantum $\Phi_0/2$ threads the wire's cross-section. Here we explore the expected topological transition in TI-wire-based Josephsonβ¦Β Expand

We have seen how the conductivity of a metal is limited by collisions, which determine the electron mean free path. After a collision, an electron completely loses all memory of its quantum state asβ¦ Expand
