Ref. Code: 32083

The project aims to exploit the laws of thermodynamics and realize thermo-machines at the ultimate limit of a single atom [1,2,3]. Utilizing state-of-the art techniques in single-ion trapping and laser state manipulation, our previous experiments have demonstrated a full Otto-cycle heat engine using a single Calcium ion in a linear Paul trap [1]. This experiment opened a new realm for investigating thermodynamics at the single-atom level and in the quantum regime. Throughout this project we seek to provide experimental answers to many interesting questions when thermo-dynamics meet the quantum world.
