Predictive Maxwell's Demons

TL;DR

This paper investigates how predictive Maxwell's demons, capable of forecasting future states, outperform non-predictive demons in heat and mass transport efficiency, with performance depending on response time, foresight, and gas density.

Contribution

It introduces a model of finite-response-time predictive Maxwell's demons and analyzes their efficiency compared to non-predictive counterparts.

Findings

Predictive demons achieve higher transport rates over time.

Performance improves with increased future sight and reduced response time.

Efficiency varies with gas density and demon's predictive capabilities.

Abstract

Here we study the operation efficiency of a finite-size finite-response-time Maxwell's demon, who can make future predictions. We compare the heat and mass transport rate of predictive demons to non-predictive ones and find that predictive demons can achieve higher mass and heat transport rates over longer periods of time. We determine how the demon performance varies with response time, future sight, and the density of the gasses on which they operate.
