| Abstract: |
Maxwell's demon cannot achieve a violation of the Second Law
of thermodynamics because of the thermodynamic cost of information erasure (known as Landauer's principle). This suggests a new statement of the Second Law, one that is provably equivalent to more familiar versions: No process can have as its sole result the erasure of information. The connection between information and thermodynamics is made even stronger by some recent theorems in non-equilibrium statistical mechanics. The Jarzynski identity, which governs the amount of work done in a non-equilibrium process, can be generalized in a natural way to encompass processes that either acquire or dispose of information. Numerical experiments confirm this new information identity. |
