Abstract / Description: 

Majorana fermion is a hypothetical fermionic particle which is its own anti-particle. Intense research efforts focus on its experimental observation as a fundamental particle in high energy physics and as a quasi-particle in condensed matter systems. I shall report the theoretical prediction and the experimental discovery of the chiral Majorana fermion in a topological state of quantum matter. In the hybrid system of a quantum anomalous Hall thin film coupled with a conventional superconductor, a series of topological phase transitions are controlled by the reversal of the magnetization, where the half-integer quantized conductance plateau (0.5e2/h) is observed as a compelling signature of the Majorana fermion.
