Potential landscape of high dimensional nonlinear stochastic dynamics with large noise

Y Tang, R Yuan, G Wang, X Zhu, P Ao - Scientific reports, 2017 - nature.com
Quantifying stochastic processes is essential to understand many natural phenomena,
particularly in biology, including the cell-fate decision in developmental processes as well as …

Role of interactions in nonequilibrium transformations

M Rose, SK Manikandan - Physical Review E, 2024 - APS
For arbitrary nonequilibrium transformations in complex systems, we show that the distance
between the current state and a target state can be decomposed into two terms: one …

Entropy production and heat transport in harmonic chains under time-dependent periodic drivings

BAN Akasaki, MJ de Oliveira, CE Fiore - Physical Review E, 2020 - APS
Using stochastic thermodynamics, the properties of interacting linear chains subject to
periodic drivings are investigated. The systems are described by Fokker-Planck-Kramers …

Endogenous molecular-cellular network cancer theory: A systems biology approach

G Wang, R Yuan, X Zhu, P Ao - Systems Biology, 2018 - Springer
In light of ever apparent limitation of the current dominant cancer mutation theory, a
quantitative hypothesis for cancer genesis and progression, endogenous molecular-cellular …

[HTML][HTML] Jarzyski's equality and crooks' fluctuation theorem for general markov chains with application to decision-making systems

P Hack, S Gottwald, DA Braun - Entropy, 2022 - mdpi.com
We define common thermodynamic concepts purely within the framework of general Markov
chains and derive Jarzynski's equality and Crooks' fluctuation theorem in this setup. In …

Anomalous free energy changes induced by topology

Y Tang, R Yuan, P Ao - Physical Review E, 2015 - APS
We report that nontrivial topology of a driven Brownian particle restricted on a ring leads to
anomalous behaviors on free energy change. Starting from steady states with identical …

Generating transverse response explicitly from harmonic oscillators

Y Yao, Y Tang, P Ao - Physical Review B, 2017 - APS
We obtain stochastic dynamics from a system-plus-bath mechanism as an extension of the
Caldeira-Leggett (CL) model in the classical regime. An effective magnetic field and …

Bounding free energy difference with flow matching

L Zhao, L Wang - Chinese Physics Letters, 2023 - iopscience.iop.org
We introduce a method for computing the Helmholtz free energy using the flow matching
technique. Unlike previous work that utilized flow-based models for variational free energy …
