Abstract

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