Z2-protected Majorana vortex end modes appear in time-reversal invariant higher-order topological insulators and in topologically trivial insulators with all surfaces gapped when chemical potential lies between the two single-TI critical values.
SQUID measurements on multilayer WTe2 show asymmetric interference patterns and a sawtooth current-phase relation at the edge, indicating ballistic supercurrent over 600 nm as evidence for second-order topological insulator character.
