Nonequilibrium fluctuation response relation in a time scale separated system
Shou-Wen Wang, Kyogo Kawaguchi, Shin-ichi Sasa +1
We present a theoretical framework to analyze the violation of fluctuation-response relation (FRR) for any observable from a finite Markov system with two well-separated time scale…
Unattainability of Carnot efficiency in thermal motors: Coarse-graining and entropy production of Feynman-Smoluchowski ratchet
Yohei Nakayama, Kyogo Kawaguchi, Naoko Nakagawa
We revisit and analyze the thermodynamic efficiency of the Feynman-Smoluchowski (FS) ratchet, a classical thought experiment describing an autonomous heat-work converter. Starting…
Topological defect launches 3D mound in the active nematic sheet of neural progenitors
Kyogo Kawaguchi, Ryoichiro Kageyama, Masaki Sano
Cultured stem cells have become a standard platform not only for regenerative medicine and developmental biology but also for biophysical studies. Yet, the characterization of cult…
Dynamical Crossover in a Stochastic Model of Cell Fate Decision
Hiroki Yamaguchi, Kyogo Kawaguchi, Takahiro Sagawa
We study the asymptotic behaviors of stochastic cell fate decision between proliferation and differentiation. We propose a model of a self-replicating Langevin system, where cells…
Entropy production of nano systems with timescale separation
Shou-Wen Wang, Kyogo Kawaguchi, Shin-ichi Sasa +1
Energy flow in bio-molecular motors and machines are vital to their function. Yet experimental observations are often limited to a small subset of variables that participate in ene…
