Thermodynamic efficiency of communication channels
Nahuel Freitas, Pedro E. Harunari, Massimiliano Esposito
We identify a broad class of communication channels that captures common physical constraints in both artificial and natural systems and derive bounds on their thermodynamic cost.…
Emergent Second Law for Time-Dependent Nonequilibrium States
Nahuel Freitas, Timur Aslyamov, Massimiliano Esposito
For nonautonomous open systems described by macroscopic stochastic thermodynamics, we derive an emergent second law that constrains time-dependent macroscopic fluctuations by the e…
Taming non-equilibrium thermal fluctuations in subthreshold CMOS circuits
Nahuel Freitas, Geremia Massarelli, Jeremy Rothschild +5
As CMOS technology scales down, thermal fluctuations increasingly impact circuit behavior, posing challenges to conventional circuit design. However, the inherent stochasticity int…
Dissipation-Reliability Tradeoff for Stochastic CMOS Bits in Series
Cathryn P. Murphy, Schuyler B. Nicholson, Nahuel Freitas +2
Physical instantiations of a bit of information are subject to thermal noise that can trigger unintended bit-flip errors. Bits implemented with CMOS technology typically operate in…
Improved diffusive approximation of Markov jump processes close to equilibrium
David Roberts, Trevor McCourt, Geremia Massarelli +2
Diffusive approximations of Markov jump processes often fail to accurately capture large fluctuations. This is confounding, as the rare events triggered by these large fluctuations…
Hypergraph-Based Models of Random Chemical Reaction Networks: Conservation Laws, Connectivity, and Percolation
Shesha Gopal Marehalli Srinivas, Massimiliano Esposito, Nahuel Freitas
Random graph models have been instrumental in characterizing complex networks, but chemical reaction networks (CRNs) are better represented as hypergraphs. Traditional models of ra…

Ashwin Gopal, Nahuel Freitas, Massimiliano Esposito
We extend the principles of information thermodynamics to study energy and information exchanges between coupled systems composed of one part undergoing a Markov jump process and a…
Bridging Freidlin-Wentzell large deviations theory and stochastic thermodynamics
Davide Santolin, Nahuel Freitas, Massimiliano Esposito +1
For overdamped Langevin systems subjected to weak thermal noise and nonconservative forces, we establish a connection between Freidlin-Wentzell large deviations theory and stochast…
Is stochastic thermodynamics the key to understanding the energy costs of computation?
David Wolpert, Jan Korbel, Christopher Lynn +16
The relationship between the thermodynamic and computational characteristics of dynamical physical systems has been a major theoretical interest since at least the 19th century, an…
Thermodynamic cost of precise timekeeping in an electronic underdamped clock
Ashwin Gopal, Massimiliano Esposito, Nahuel Freitas
Clocks are inherently out-of-equilibrium because, due to friction, they constantly consume free energy to keep track of time. The Thermodynamic Uncertainty Relation (TUR) quantifie…
A chemical reaction network implementation of a Maxwell demon
Massimo Bilancioni, Massimiliano Esposito, Nahuel Freitas
We study an autonomous model of a Maxwell demon that works by rectifying thermal fluctuations of chemical reactions. It constitutes the chemical analog of a recently studied electr…
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…
Information flows in macroscopic Maxwell's demons
Nahuel Freitas, Massimiliano Esposito
A CMOS-based implementation of an autonomous Maxwell's demon was recently proposed (Phys. Rev. Lett. 129, 120602) to demonstrate that a Maxwell demon can still work at macroscopic…
Circuit Theory for Chemical Reaction Networks
Francesco Avanzini, Nahuel Freitas, Massimiliano Esposito
We lay the foundation of a circuit theory for chemical reaction networks. Chemical reactions are grouped into chemical modules solely characterized by their current-concentration c…
Large deviations theory for noisy non-linear electronics: CMOS inverter as a case study
Ashwin Gopal, Massimiliano Esposito, Nahuel Freitas
The latest generation of transistors are nanoscale devices whose performance and reliability are limited by thermal noise in low-power applications. Therefore developing efficient…
A Maxwell demon that can work at macroscopic scales
Nahuel Freitas, Massimiliano Esposito
Maxwell's demons work by rectifying thermal fluctuations. They are not expected to function at macroscopic scales where fluctuations become negligible and dynamics become determini…
