Can you help me to extend the BCS theory developed in Thermo Dynamics (TFD) formalism to high-temperature superconductivity?
nihad said:excuse me, BCS theory developed in Thermo field dynamics (TFD), I merely as a source the article "Derivation and application of the boson method in superconductivity" L.Leplae and all, but the method is developed for the conventional superconductivity. I want apply this method to high temperature superconductivity but I don't Know how to do?

This method is completely different to BEC method.
BCS theory in thermo field dynamics is a theoretical framework used to study superconductivity at finite temperatures. It combines the concepts of BCS theory, which explains superconductivity at absolute zero temperature, with thermo field dynamics, which is a mathematical tool used to describe quantum systems at finite temperatures.
BCS theory in thermo field dynamics explains superconductivity as a result of electrons forming Cooper pairs, which are pairs of electrons with opposite spin and momentum. These Cooper pairs then condense into a macroscopic quantum state, leading to the loss of electrical resistance and other unique properties of superconductors.
Studying BCS theory in thermo field dynamics allows scientists to understand the behavior of superconductors at temperatures above absolute zero, where most real-world applications of superconductors occur. It also helps to explain the underlying mechanisms of superconductivity and can lead to the discovery of new materials with enhanced superconducting properties.
One challenge in applying BCS theory in thermo field dynamics is that it involves complex mathematical calculations, making it difficult to obtain exact solutions for certain systems. Another challenge is that the theory does not account for all types of superconductors, such as high-temperature superconductors, which require more advanced theories for explanation.
BCS theory in thermo field dynamics has evolved over time through advancements in quantum field theory and the development of new techniques, such as mean-field theories and renormalization group methods. These advancements have allowed for a deeper understanding of superconductivity and have led to new insights and predictions about the behavior of superconductors.
