Superconductivity Is Unpredictable at the Edge

A recent study shows that the superconducting edge currents in the topological material molybdenum telluride (MoTe2) can sustain large changes in the “glue” that keeps the superconducting electrons paired. To sustain these changes, the bulk and the edge of MoTe2 must behave differently. This surprise finding will help researchers create and control anyons and aid in the development of future energy-efficient electronics.
