Abstract

We discuss a number of experiments that could detect the electron edge states in the organic quasi-one-dimensional conductors (TMTSF)₂X and the inorganic quasi-two-dimensional perovskites Sr₂RuO₄. We consider the chiral edges states in the magnetic-field-induced spin-density-wave (FISDW) phase of (TMTSF)₂X and in the time-reversal-symmetry-breaking triplet superconducting phase of Sr₂RuO₄, as well as the nonchiral midgap edge states in the triplet superconducting phase of (TMTSF)₂X. The most realistic experiment appears to be an observation of spontaneous magnetic flux at the edges of Sr₂RuO₄ by a scanning SQUID microscope.
