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 Murphy, Schuyler 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…
Information thermodynamics for Markov jump processes coupled to underdamped diffusion: Application to nanoelectromechanics
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…
