Majorana fermions are "real" fermions with their antiparticles as

themselves. The search for Majorana fermions in high energy physics is

long. Neutrinos are thought by some theorest to be Majorana fermions, but

nothing is sure. In condensed matter physics, Majorana fermions could

appear as some kind of quasiparticles. And this bizarre collective

excitation is responsible for a lot of interesting phenomena: fermion zero

mode, non-local edge states, non-abliean anyons, etc..

In this seminar, I would like to tell some basic physics underlying

Majorana fermions, and then discuss a simple and well-known model of

spinless p-wave superconductor in which Marorana zero mode could appear

naturally. Finally, some analogues models related to topological insulators

will be talked.
