Analysis
This paper offers a novel axiomatic approach to thermodynamics, building it from information-theoretic principles. It's significant because it provides a new perspective on fundamental thermodynamic concepts like temperature, pressure, and entropy production, potentially offering a more general and flexible framework. The use of information volume and path-space KL divergence is particularly interesting, as it moves away from traditional geometric volume and local detailed balance assumptions.
Key Takeaways
- •Develops an axiomatic reconstruction of thermodynamics based on information theory.
- •Introduces 'information volume' and uses it to define pressure.
- •Characterizes entropy production through relative-entropy asymmetry.
- •Defines heat without relying on local detailed balance or specific bath models.
