Since the discovery of the high‐ T c cuprate superconductor La 2– x BaCuO 4 in 1986 by Bednorz and Müller, controversy regarding the nature or origin of this remarkable superconductivity has continued. However, d‐wave superconductivity in the hole‐doped cuprates, arising due to the anti‐paramagnon exchange, was established around 1994. More recently we have shown that the mean field theory, like the BCS theory of superconductivity and Landau's Fermi liquid theory are adequate to describe the cuprates. The keys for this development are the facts that a) the pseudogap phase is d‐wave density wave (dDW) and that the high‐ T c cuprate superconductivity is gossamer (i.e. it exists in the presence of dDW).
