Explain the resistivity for high-temperature superconductivity on YBCO compounds using string theory and Schrödinger equation

Super conductors play an important role in our day life. they are widely used in generation of powerful magnetic and electrical energy, transportation and magnetic resonance imaging. This encourages to construct a new model based on the laws of fluid mechanics. In this model a new energy expression including the pressure which is related to the thermal energy was found. This expression was used to find the electric resistance. The model indicated that the resistance vanishes and the material becomes a super conductor when the temperature is less than a certain critical value. This critical temperature was found to be dependent on the internal and external fields including electric and magnetic fields. This may explain why a wide variety of materials can act as a super conductor. Schrödinger equation was also utilized to obtain a useful expression for the resistance dependent on the wave number. The conditions for super conducting conditions indicated that the material becomes a superconductor when the temperature is less than a certain critical temperature which is dependent on the internal and external fields. using quantum laws indicated that such conditions can explain the behavior of nano materials.
