Thermodynamics of computations with absolute irreversibility, unidirectional transitions, and stochastic computation times
Gonzalo Manzano, Gülce Kardeş, Édgar Roldán +1
Developing a thermodynamic theory of computation is a challenging task at the interface of non-equilibrium thermodynamics and computer science. In particular, this task requires de…
Stochastic thermodynamics of multiple co-evolving systems -- beyond multipartite processes
Farita Tasnim, David H. Wolpert
Many dynamical systems consist of multiple, co-evolving subsystems (degrees of freedom). These subsystems often depend upon each other in a way that restricts the overall system's…
Entropy production in communication channels
Farita Tasnim, Nahuel Freitas, David H. Wolpert
In many complex systems, whether biological or artificial, the thermodynamic costs of communication among their components are large. These systems also tend to split information t…
Nonequilibrium thermodynamics of uncertain stochastic processes
Jan Korbel, David H. Wolpert
Stochastic thermodynamics is formulated under the assumption of perfect knowledge of all thermodynamic parameters. However, in any real-world experiment, there is non-zero uncertai…
Combining lower bounds on entropy production in complex systems with multiple interacting components
David H. Wolpert
The past two decades have seen a revolution in statistical physics, generalizing it to apply to systems of arbitrary size, evolving while arbitrarily far from equilibrium. Many of…
Thermodynamics of deterministic finite automata operating locally and periodically
Thomas E. Ouldridge, David H. Wolpert
Real-world computers have operational constraints that cause nonzero entropy production (EP). In particular, almost all real-world computers are ``periodic'', iteratively undergoin…
Inclusive Thermodynamics of Computational Machines
Gülce Kardeş, David Wolpert
We introduce a framework designed to analyze the thermodynamics of an abstractly defined logical computer like a deterministic finite automaton (DFA) or a Turing machine, without s…
Thermodynamic speed limits for co-evolving systems
Farita Tasnim, David H. Wolpert
Previously derived "global" thermodynamic speed limit theorems state that increasing the maximum speed with which a system can evolve between two given probability distributions ov…
Entropy production given constraints on the energy functions
Artemy Kolchinsky, David H. Wolpert
We consider the problem of driving a finite-state classical system from some initial distribution to some final distribution with vanishing entropy production (EP), under…
Thermodynamics of nonequilibrium systems with uncertain parameters
Jan Korbel, David H. Wolpert
In the real world, one almost never knows the parameters of a thermodynamic process to infinite precision. Reflecting this, here we investigate how to extend stochastic thermodynam…
Thermodynamic Uncertainty Relations for Multipartite Processes
Gülce Kardeş, David H. Wolpert
The thermodynamic uncertainty relations (TURs) provide lower bounds on the entropy production (EP) of a system in terms of the statistical precision of an arbitrary current in that…
Stochastic thermodynamics and fluctuation theorems for non-linear systems
Jan Korbel, David H. Wolpert
We extend stochastic thermodynamics by relaxing the two assumptions that the Markovian dynamics must be linear and that the equilibrium distribution must be a Boltzmann distributio…
Strengthened second law for multi-dimensional systems coupled to multiple thermodynamic reservoirs
David H. Wolpert
The second law of thermodynamics can be formulated as a restriction on the evolution of the entropy of any system undergoing Markovian dynamics. Here I show that this form of the s…
Fluctuation theorems for multiple co-evolving systems
David H. Wolpert
All previously derived thermodynamic fluctuation theorems (FTs) that concern multiple co-evolving systems have required that each system can only change its state during an associa…
Minimal entropy production due to constraints on rate matrix dependencies in multipartite processes
David H Wolpert
I consider multipartite processes in which there are constraints on each subsystem's rate matrix, restricting which other subsystems can directly affect its dynamics. I derive a st…
Thermodynamic costs of Turing Machines
Artemy Kolchinsky, David H. Wolpert
Turing Machines (TMs) are the canonical model of computation in computer science and physics. We combine techniques from algorithmic information theory and stochastic thermodynamic…
Uncertainty relations and fluctuation theorems for Bayes nets
David H. Wolpert
Recent research has considered the stochastic thermodynamics of multiple interacting systems, representing the overall system as a Bayes net. I derive fluctuation theorems governin…
Stochastic thermodynamics of computation
David H. Wolpert
One of the major resource requirements of computers - ranging from biological cells to human brains to high-performance (engineered) computers - is the energy used to run them. Tho…
Overview of Information Theory, Computer Science Theory, and Stochastic Thermodynamics for Thermodynamics of Computation
David H. Wolpert
I give a quick overview of some of the theoretical background necessary for using modern non-equilibrium statistical physics to investigate the thermodynamics of computation. I fir…
Semantic information, autonomous agency, and nonequilibrium statistical physics
Artemy Kolchinsky, David H. Wolpert
Shannon information theory provides various measures of so-called "syntactic information", which reflect the amount of statistical correlation between systems. In contrast, the con…
Thermodynamics of computing with circuits
David Hilton Wolpert, Artemy Kolchinsky
Digital computers implement computations using circuits, as do many naturally occurring systems (e.g., gene regulatory networks). The topology of any such circuit restricts which v…
Number of hidden states needed to physically implement a given conditional distribution
Jeremy A. Owen, Artemy Kolchinsky, David H. Wolpert
We consider the problem of how to construct a physical process over a finite state space that applies some desired conditional distribution to initial states to produce fin…
A space-time tradeoff for implementing a function with master equation dynamics
David H. Wolpert, Artemy Kolchinsky, Jeremy A. Owen
Master equations are commonly used to model the dynamics of physical systems, including systems that implement single-valued functions like a computer's update step. However, many…
When is a bit worth much more than kT ln2?
Can Gokler, Artemy Kolchinsky, Zi-Wen Liu +6
Physical processes thatobtain, process, and erase information involve tradeoffs between information and energy. The fundamental energetic value of a bit of information exchanged wi…
