Description
This talk focuses on two distinct but related experiments in thermal systems. The first is an experimental demonstration of optimal transport in thermal systems using a microscopic particle trapped by optical tweezers. In particular, we achieve the optimal transport of translation and Landauer erasure that reaches the finite-speed thermodynamic minimum of the entropy production. The second is the experimental exploration of the efficient control of a single-molecule molecular motor F1-ATPase. This motor is forcedly rotated in cells to generate ATP molecules. However, it remains unclear how the motor is rotated. To partially answer this question, we experimentally compare the work necessary to rotate the motor by different torque modes. The results highlight the importance of suppressing nonequilibrium fluctuations for efficient control.
