Learning force fields from stochastic trajectories

A Frishman, P Ronceray - Physical Review X, 2020 - APS
When monitoring the dynamics of stochastic systems, such as interacting particles agitated
by thermal noise, disentangling deterministic forces from Brownian motion is challenging …

Inferring scale-dependent non-equilibrium activity using carbon nanotubes

A Bacanu, JF Pelletier, Y Jung, N Fakhri - Nature Nanotechnology, 2023 - nature.com
In living systems, irreversible, yet stochastic, molecular interactions form multiscale
structures (such as cytoskeletal networks), which mediate processes (such as cytokinesis …

Distribution of the time of the maximum for stationary processes

F Mori, SN Majumdar, G Schehr - Europhysics Letters, 2021 - iopscience.iop.org
We consider a one-dimensional stationary stochastic process x (τ) of duration T. We study
the probability density function (PDF) P (tm| T) of the time tm at which x (τ) reaches its global …

Log-normal turbulence dissipation in global ocean models

B Pearson, B Fox-Kemper - Physical review letters, 2018 - APS
Data from turbulent numerical simulations of the global ocean demonstrate that the
dissipation of kinetic energy obeys a nearly log-normal distribution even at large horizontal …

Learning the non-equilibrium dynamics of Brownian movies

FS Gnesotto, G Gradziuk, P Ronceray… - Nature …, 2020 - nature.com
Time-lapse microscopy imaging provides direct access to the dynamics of soft and living
systems. At mesoscopic scales, such microscopy experiments reveal intrinsic thermal and …

Heterogeneous out-of-equilibrium nonlinear -voter model with zealotry

A Mellor, M Mobilia, RKP Zia - Physical Review E, 2017 - APS
We study the dynamics of the out-of-equilibrium nonlinear q-voter model with two types of
susceptible voters and zealots, introduced in Mellor et al.[Europhys. Lett. 113, 48001 (2016) …

Nonequilibrium oscillations, probability angular momentum, and the climate system

JB Weiss, B Fox-Kemper, D Mandal, AD Nelson… - Journal of Statistical …, 2020 - Springer
Abstract Though the Boltzmann–Gibbs framework of equilibrium statistical mechanics has
been successful in many arenas, it is clearly inadequate for describing many interesting …

Learning dynamical models from stochastic trajectories

P Ronceray - arXiv preprint arXiv:2406.02363, 2024 - arxiv.org
The dynamics of biological systems, from proteins to cells to organisms, is complex and
stochastic. To decipher their physical laws, we need to bridge between experimental …

Autoregressive statistical modeling of a peru margin multi-proxy holocene record shows correlation not causation, flickering regimes and persistence

S Ahn, B Fox-Kemper, T Herbert, M Altabet… - Journal of Statistical …, 2020 - Springer
Correlation does not necessarily imply a causation, but in climatology and paleoclimatology,
correlation is used to identify potential cause-and-effect relationships because linking …
