Superconductors and insulators are condensed matters with opposite transport properties. It is interesting that high-temperature and organic superconductors are observed on the verge of some special type of insulators called Mott insulators, where the insulating behaviour is caused by electron correlations. In this talk I will examine the phase transition between the Mott insulator and such a superconductor, also called a gossamer superconductor for its tiny superfluidity density. I will also examine the connection between gossamer superconductivity and the resonating valence bond state.
