My research interests

Research Interests. My principal research interests are in the mathematical structures of Quantum Statistical Mechanics, Condensed Matter Physics, Superconductivity and Superfluidity, Relativistic Quantum Theory and the Quantum Theory of Measurement. 



I have published two books and numerous research articles.
