Abstract: It was surprising that a single impurity spin coupled to a Fermi gas in a metal, produces resistance minimum at low temperatures. It took 30 years from the first observation in Leiden and Jun Kondo gave a plausible explanation, known after his name. Since then the Kondo problem has played a massive role in many body physics over the years, both for the methods required to solve it, and because it kept popping up in different guises. In the context of explaining certain anomaly in the conductance of quasi-one dimensional metals (ref. to my first talk), Kondo effect is an attractive candidate in recent years. Besides the application to mesoscopic physics, I shall highlight novel features like Kondo insulators, charge and spin Kondo effect and topological Kondo effect.
