摘要
We introduce a deterministic chaotic system-the Szilard map-that encapsulates the measurement, control, and erasure protocol by which Maxwellian demons extract work from a heat reservoir. Implementing the demon's control function in a dynamical embodiment, our construction symmetrizes the demon and the 熱力學 system, allowing one to explore their functionality and recover the fundamental trade-off between the 熱力學 costs of dissipation due to measurement and those due to erasure. The map's degree of 混沌-captured by the Kolmogorov-Sinai 熵-is the rate of energy extraction from the heat bath. Moreover, an engine's 統計 complexity quantifies the minimum necessary system memory for it to function. In this way, dynamical instability in the control protocol plays an essential and constructive role in int
