    ABSTRACT
     

    Majorana fermions are real solution of Dirac equation, in opposite to the Dirac fermions as complex solution.  Neutrino is a candidate for Majorana particle in elementary particle physics. In this talk, I will briefly review proposed emerging Majorana particles in condensed matter systems, and Majorana zero modes in the vortex of topological superconductors, in particular, in the context of potential application in quantum computing. Recent experiments and theories on this topic will be discussed.
