Unconventional/high temperature superconductivity (SC) is observed in heavy fermion systems, cuprates, molecular crystals, and ferropnictides close to a point in the phase diagram where, as a function of a control parameter such as pressure, chemical pressure, or doping, the antiferromagnetic order is suppressed. A widespread view is that at this point, which is called a quantum critical point, strong...
