The interplay between the spin-orbit
coupling at the surface of a topological insulator (TI), the conventional pair
potential from a superconductor, and an external magnetic field creates a very
exotic induced pair potential in a TI-based
normal-superconductor junction. In addition to a superposition of
spin-singlet and triplet components, a new, unconventional type of
superconducting condensate can be induced in this system: one with a
spin-triplet component that is both odd in frequency and even in its
spatial coordinates. An unambiguous experimental detection of such
odd-frequency condensate has not been achieved.
