Abstract:Heat engines are essential devices in modern industry, converting heat energy into useful mechanical work via their working substances. Here we experimentally simulate the conventional heat engine by employing the vibrational mode of a single trapped ion as the working substance. In contrast to simply employing the ion in thermal motion, we consider to coherently stimulate the ion's vibrational motion as the phonon laser, which helps acquiring clearer results by effectively suppressing the thermal fluctuation.… Show more
