Effective estimation of entropy production with lacking data

M Baiesi, T Nishiyama, G Falasco - Communications Physics, 2024 - nature.com
Observing stochastic trajectories with rare transitions between states, practically
undetectable on time scales accessible to experiments, makes it impossible to directly …

Emergent second law for non-equilibrium steady states

JN Freitas, M Esposito - Nature Communications, 2022 - nature.com
The Gibbs distribution universally characterizes states of thermal equilibrium. In order to
extend the Gibbs distribution to non-equilibrium steady states, one must relate the self …

Maxwell demon that can work at macroscopic scales

N Freitas, M Esposito - Physical Review Letters, 2022 - APS
Maxwell's demons work by rectifying thermal fluctuations. They are not expected to function
at macroscopic scales where fluctuations become negligible and dynamics become …

Fundamental energy cost of finite-time parallelizable computing

M Konopik, T Korten, E Lutz, H Linke - Nature Communications, 2023 - nature.com
The fundamental energy cost of irreversible computing is given by the Landauer bound of k
T ln 2/bit, where k is the Boltzmann constant and T is the temperature in Kelvin. However …

Large deviations theory for noisy nonlinear electronics: CMOS inverter as a case study

A Gopal, M Esposito, N Freitas - Physical Review B, 2022 - APS
The latest generations of transistors are nanoscale devices whose performance and
reliability are limited by thermal noise in low-power applications. Therefore, developing …

Stochastic Thermodynamics of Nonlinear Electronic Circuits: A Realistic Framework for Computing Around

N Freitas, JC Delvenne, M Esposito - Physical Review X, 2021 - APS
We provide a general theory of nonlinear electronic circuits subjected to thermal noise. The
devices constituting the circuit can have arbitrary IV curves but must display shot noise. This …

On noise-induced transient bit flips in subthreshold SRAM

L Van Brandt, F Silveira, JC Delvenne, D Flandre - Solid-State Electronics, 2023 - Elsevier
We propose a rigorous SPICE simulation framework, compatible with industrial process
design kits, to observe transient bit flips in CMOS SRAM due to the intrinsic transistor noise …

Noise–dissipation relation for nonlinear electronic circuits

L Van Brandt, JC Delvenne - Applied Physics Letters, 2023 - pubs.aip.org
An extension of fluctuation–dissipation theorem is used to derive a “speed limit” theorem for
nonlinear electronic devices. This speed limit provides a lower bound on the dissipation that …
