Abstract : This paper considers the possibility of developing ultrafast thermodynamic engine cycles that operate by the exchange of internal phase heat with the environment. These engines operate on the basis of the first and second laws of thermodynamics which are written in a form where the entropy and internal energy are complex numbers which rotate in an internal space during an ultrafast process. Several types of cyclic engines are considered in which the magnitudes of both the entropy and internal energy remain fixed during each portion of the cycle. The efficiencies are calculated for internal phase engine cycles of the type: Carnot, Otto, Diesel, Stirling, Ericsson and Brayton. These efficiencies are complex numbers whose real parts represent measured efficiencies that must always be less than unity. A brief discussion is given of the application of broken symmetry internal phase engine cycles to practical power sources and to the thermodynamic processes that occur in high speed computer memories. The possibility of developing high-Tc superconducting electron-pair engines is considered.
