THE FLUCTUATION THEOREM
Abstract:
In 1993 we discovered a relation, subsequently known as the Fluctuation Theorem, which gives an analytical expression for the probability of observing Second Law violating dynamical fluctuations in small thermostatted nonequilibrium systems which are observed for a short period of time. This theorem places quantitative restrictions on the operation of small (nano) machines and devices. These constraints cannot be circumvented. Quantitative predictions made by the Fluctuation Theorem regarding the probability of Second Law violations have been confirmed experimentally, both using molecular dynamics computer simulation and very recently in two laboratory experiments which employed optical tweezers. In this talk we give a brief summary of the theory and a description of the experiments.
