Abstract: This talk will present recent experiments demonstrating routes to topological superconductivity in semiconductor-superconductor hybrids that take advantage of phase control. The first instance is in a cylindrical geometry, the transition shows up as even versus odd Caroli-deGennes-Matricon states. In a planar geometry, zero-bias features appear across a long Josephson junction subject to phase bias. Extension beyond present experiments will be considered as well.
