Abstract

This year is the golden anniversary of the theory of superconductivity of Bardeen, Cooper and Schrieffer (BCS theory). The BCS theory finds wide applicability in quantum field theory including high energy particle physics, nuclear matter, quantum chromodynamics, superfluid 3He and unconventional superconductors including high Tc superconductors. Here we shall review a few aspects of unconventional superconductors. Very recent development on half-quantum vortices (HQV) and Majorana fermions are briefly touched..

Keywords

BCS theory, High Tc superconductors, Half-quantum vertices, Majorana fermions.
