Thermodynamic Overfitting and Generalization: Energetic Limits on Predictive Complexity
Alexander B. Boyd, James P. Crutchfield, Mile Gu +1
Efficiently harvesting thermodynamic resources requires a precise understanding of their structure. This becomes explicit through the lens of information engines -- thermodynamic e…
The Thermodynamic Uncertainty Theorem
Kyle J. Ray, Alexander B. Boyd, Giacomo Guarnieri +1
Thermodynamic uncertainty relations (TURs) express a fundamental tradeoff between the precision (inverse scaled variance) of any thermodynamic current by functionals of the average…
Trajectory Class Fluctuation Theorem
Gregory Wimsatt, Alexander B. Boyd, James P. Crutchfield
The Trajectory Class Fluctuation Theorem (TCFT) substantially strengthens the Second Law of Thermodynamics -- that, in point of fact, can be a rather weak bound on resource fluxes.…
Time Symmetries of Memory Determine Thermodynamic Efficiency
Alexander B. Boyd, Paul M. Riechers, Gregory W. Wimsatt +2
While Landauer's Principle sets a lower bound for the work required for a computation, that work is recoverable for efficient computations. However, practical physical computers, s…
Refining Landauer's Stack: Balancing Error and Dissipation When Erasing Information
Gregory W. Wimsatt, Alexander B. Boyd, Paul M. Riechers +1
Nonequilibrium information thermodynamics determines the minimum energy dissipation to reliably erase memory under time-symmetric control protocols. We demonstrate that its bounds…
Non-Markovian Momentum Computing: Universal and Efficient
Kyle J. Ray, Gregory W. Wimsatt, Alexander B. Boyd +1
All computation is physically embedded. Reflecting this, a growing body of results embraces rate equations as the underlying mechanics of thermodynamic computation and biological i…
Thermodynamic Machine Learning through Maximum Work Production
A. B. Boyd, J. P. Crutchfield, M. Gu
Adaptive systems -- such as a biological organism gaining survival advantage, an autonomous robot executing a functional task, or a motor protein transporting intracellular nutrien…
Balancing Error and Dissipation in Computing
P. M. Riechers, A. B. Boyd, G. W. Wimsatt +1
Modern digital electronics support remarkably reliable computing, especially given the challenge of controlling nanoscale logical components that interact in fluctuating environmen…
Harnessing Fluctuations in Thermodynamic Computing via Time-Reversal Symmetries
Gregory Wimsatt, Olli-Pentti Saira, Alexander B. Boyd +4
We experimentally demonstrate that highly structured distributions of work emerge during even the simple task of erasing a single bit. These are signatures of a refined suite of ti…
Shortcuts to Thermodynamic Computing: The Cost of Fast and Faithful Erasure
A. B. Boyd, A. Patra, C. Jarzynski +1
Landauer's Principle states that the energy cost of information processing must exceed the product of the temperature and the change in Shannon entropy of the information-bearing d…
Above and Beyond the Landauer Bound: Thermodynamics of Modularity
Alexander B. Boyd, Dibyendu Mandal, James P. Crutchfield
Information processing typically occurs via the composition of modular units, such as universal logic gates. The benefit of modular information processing, in contrast to globally…
Transient Dissipation and Structural Costs of Physical Information Transduction
Alexander B. Boyd, Dibyendu Mandal, Paul M. Riechers +1
A central result that arose in applying information theory to the stochastic thermodynamics of nonlinear dynamical systems is the Information-Processing Second Law (IPSL): the phys…
Leveraging Environmental Correlations: The Thermodynamics of Requisite Variety
Alexander B. Boyd, Dibyendu Mandal, James P. Crutchfield
Key to biological success, the requisite variety that confronts an adaptive organism is the set of detectable, accessible, and controllable states in its environment. We analyze it…
Correlation-powered Information Engines and the Thermodynamics of Self-Correction
Alexander B. Boyd, Dibyendu Mandal, James P. Crutchfield
Information engines can use structured environments as a resource to generate work by randomizing ordered inputs and leveraging the increased Shannon entropy to transfer energy fro…
Memoryless Thermodynamics? A Reply
Dibyendu Mandal, Alexander B. Boyd, James P. Crutchfield
We reply to arXiv:1508.00203 `Comment on "Identifying Functional Thermodynamics in Autonomous Maxwellian Ratchets" (arXiv:1507.01537v2)'.
Identifying Functional Thermodynamics in Autonomous Maxwellian Ratchets
A. B. Boyd, D. Mandal, J. P. Crutchfield
We introduce a family of Maxwellian Demons for which correlations among information bearing degrees of freedom can be calculated exactly and in compact analytical form. This allows…
Demon Dynamics: Deterministic Chaos, the Szilard Map, and the Intelligence of Thermodynamic Systems
Alexander B. Boyd, James P. Crutchfield
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…
