【 摘 要 】

We investigate the adiabatic evolution of the thermal state in nonreciprocal many-body systems coupled to their environment and subject to periodic drivings. In such systems we show that besides the dynamical phase a geometrical phase can exist and it drives the relaxation dynamic of the system. In contrast to the dynamical phase which always pushes the system toward its equilibrium state we show that the geometric phase can speed up or reduce the speed of the relaxation process. These results could have applications in the field of thermal management of complex systems.
