Emergence of fluctuation relations in UNO

open access: yesPhysical Review Research
In the last two decades, fluctuation theorems have been proved formally and demonstrated experimentally for several variables (such as entropy production, work, or flux) and different noises causing the fluctuations (of either thermal or other origin ...

Non-Markovian quantum thermodynamics: laws and fluctuation theorems

open access: yes, 2018
International audienceThis work brings together thermodynamics and nonequilibrium quantum theory, by showing that a real-time diagrammatic technique on the Keldysh contour is an equivalent of stochastic thermodynamics for non-Markovian quantum machines ...

Two refreshing views of Fluctuation Theorems through Kinematics Elements and Exponential Martingale [PDF]

open access: yes, 2011
International audienceIn the context of Markov evolution, we present two original approaches to obtain Generalized Fluctuation-Dissipation Theorems (GFDT), by using the language of stochastic derivatives and by using a family of exponential martingales ...

Automating Chemical Reasoning in High‐Throughput Phase Identification With a Probabilistic, LLM‐Guided Framework

open access: yesAdvanced Science, EarlyView.
Autonomous laboratories can now synthesize materials faster than experts can interpret the resulting diffraction data. A probabilistic framework combines refinement‐fit metrics with large language model‐derived chemical reasoning to rank competing phase interpretations and flag those unsuitable for autonomous use.

From free energy measurements to thermodynamic inference in nonequilibrium small systems

open access: yesNew Journal of Physics, 2015
Fluctuation theorems (FTs), such as the Crooks or Jarzynski equalities (JEs), have become an important tool in single-molecule biophysics where they allow experimentalists to exploit thermal fluctuations and measure free-energy differences from non ...

Free energy measurements by the generalized fluctuation theorems: Theory and numerical study of a model filament

open access: yes, 2020
We measure the free energy of a model filament, which undergoes deformations and structural transitions, as a function of its extension, in silico.

Lipidomic Profile Reconstruction of Therapeutic Membrane Targets Using Physics‐Based Optimization with Limited Activity Data

open access: yesAdvanced Science, EarlyView.
Using a minimal set of experimentally labeled antimicrobial and non‐antimicrobial peptides, we reconstruct the effective lipid composition of a pathogenic membrane ‐demonstrated at the example of bacterial membranes‐ through a physics‐based evolutionary molecular dynamics (Evo‐MD) approach. Optimization based on peptide insertion reveals broad‐spectrum

Quantum nonequilibrium equalities with absolute irreversibility

open access: yesNew Journal of Physics, 2015
We derive quantum nonequilibrium equalities in absolutely irreversible processes. Here by absolute irreversibility we mean that in the backward process the density matrix does not return to the subspace spanned by those eigenvectors that have nonzero ...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

open access: yesAdvanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Variational Approach to KPZ: Fluctuation Theorems, Large Deviation Function for Entropy Production & Probability Distribution Function

open access: yes, 2021
MECO45 will be organized as an online conference on 14-16 September, 2020.Motivated by the time behavior of the functional arising in the variational approach to the KPZ equation [1] [2], and in order to study fluctuation theorems in such a system, we ...
