Majorana fermion detected in a quantum layer cake

Topological insulator plus superconductor yields new evidence for unusual quasiparticle

Majorana fermions in a topological insulator

MAJORANAS IN MOTION  Majorana fermions (blue, red, and purple lines) travel through a topological insulator (horizontal bar) with a superconductor layered on top in this illustration of new experiments to detect the fermions. Green lines indicate electrons travelling on the edges of the topological insulator.
