Quantum Phase Transition Schematic (IMAGE) University of Utah Caption This schematic diagram shows the quantum phase transition of a superconducting metal to a normal metal at zero temperature. As the magnetic field increases in strength, the superconductivity breaks down until the critical point at which the material becomes a normal metal.
