Review of thermodynamics concerning phase transitions (How to increase high temperature superconductivity via quantum entanglement)

We review thermodynamic 4 variables and potentials, recommend precision optics interference. Measurement techniques for the phase transitions as follows. consider superconductivity a Lambda (close to 2nd order) transition phenomena. Then quantum mechanics entanglement of two branches superconductor wires that are made YBCO 123 high temperature can be further increased one wire toward room while still kept at zero resistance Ohm’s law measured by Optics Phase Conjugated Interferometer.
