    • Scope

    So far, currents generated by geometric phases in periodically driven systems have been discussed, but their application to heat engines has not been addressed. In addition, athermal systems such as driven powders and colloids have been studied as individual theories, but there has been a lack of perspectives to pursue their universality. The purpose of this study is to clarify the role of geometrical phases and their generating currents by advancing the theory of heat engines of microsystems when periodically driven, and to analyze the non-equilibrium phase transitions of driven athermal dissipative many-body systems from a unified viewpoint. In this study, the theory of heat engine is clarified by using the theory of Markov process. For the analysis of non-thermal systems, we will construct a theory of non-equilibrium solid-liquid phase transitions using solid-based and liquid-based theories, and at the same time, we will clarify the mechanism of the anomalous relaxation phenomena that appear in such systems. The aim of this study is to provide not only a new physical perspective on a wide class of driven nonequilibrium systems, but also useful information for a wide range of applications. In addition to providing a new physical perspective on a wide class of driven nonequilibrium systems, the objective of this research is to provide useful information for a wide range of applications.
