According to the physicist organization network reported on the 21st, an international team led by theoretical physicists at Trinity College Dublin, Ireland, built the world's smallest engine-a single calcium ion, whose volume is only 10 parts per billion One. This equipment can be incorporated into other technologies in the future to recover waste heat, thereby improving energy efficiency. The engine itself is a single charged calcium ion, which makes it easy to be captured by the electric field. The working unit of the engine is the "intrinsic spin" (angular momentum) of the ions. This spin converts the heat absorbed from the laser beam into the vibration of the trapped ions. Researchers say these vibrations are like a "flywheel" that captures the useful energy generated by the engine. As predicted by quantum mechanics, this energy is stored in discrete units called "quantum". Dr. Mark Mitchison of Trinity College said: "The 'flywheel' allows us to actually measure the power output of an atomic-scale engine and solve the problem of a single energy range for the first time." The "flywheel" starts at rest, or more precisely, its "ground state" (the lowest energy in quantum physics). The team observed that this small engine forced the "flywheel" to run faster and faster. It is particularly important that the ion state can be obtained in experiments, which allows physicists to accurately assess the energy deposition process. John Goethe, an assistant professor of physics at Trinity College, said: "This experiment and theoretical study opened a new era for the study of technical energy based on quantum theory, which is the core topic of our group's research. Nanoscale thermal management is faster , One of the basic bottlenecks for more efficient calculations. Understanding how thermodynamics is applied to such a micro-environment is critical to future technologies. " Related research was published in the latest issue of Physics Review Letters.
