Recent theories of \u201ctopological insulators\u201d [1,2] have shown that in the complex and emergent world of condensed matter physics, one can engineer the interplay between fundamental symmetries, band structure and spin-orbit coupling to create novel energy-spin-momentum relationships for band electrons and to yield effective realizations of exotic particles predicted but yet unobserved in Nature. \u0026nbsp;This Colloquium will describe the experimental routes we are pursuing in this context to build \u0022detectors\u0022 for such particles, by coupling the surface states of a topological insulator with the gauge symmetry breaking effects of superconductivity [3] and the time-reversal symmetry breaking effect of magnetism [4.5]. \u003Cbr \/\u003E1.
