Abstract

An experimental demonstration of a second-law-like theorem to explain the time-reversible microscopic equations was presented. The second-law-like theorem was found to bridge the gap between microscopic and macroscopic domains. It was also found to link time-reversible and irreversible descriptions. The theorem was applied to a colloidal particle in an optical trap.
