Breakdown of the Overdamped Approximation in Fluctuating Environments
Kazuki Fukutani, Takuma Akimoto
The overdamped approximation is widely used to describe Brownian motion in complex environments, but its validity becomes nontrivial when the friction coefficient itself fluctuates…
Anomalous statistics in the Langevin equation with fluctuating diffusivity: from Brownian yet non-Gaussian diffusion to anomalous diffusion and ergodicity breaking
Takuma Akimoto, Jae-Hyung Jeon, Ralf Metzler +3
Diffusive motion is a fundamental transport mechanism in physical and biological systems, governing dynamics across a wide range of scales -- from molecular transport to animal for…
Unveiling Optimal Diffusion for Infection Control in Brownian Particle Systems
Kaito Takahashi, Makiko Sasada, Takuma Akimoto
Understanding the spread of infectious diseases requires integrating movement, physical constraints, and spatial configurations into epidemiological models. In this study, we inves…
Unexpected Effects of Disorder on Current Fluctuations in the Symmetric Simple Exclusion Process
Issei Sakai, Takuma Akimoto
We explore how the disorder impacts the current fluctuations in the symmetric simple exclusion process (SSEP) within a heterogeneous environment. First, we analyze the SSEP with a…
Diffusion of intrinsically disordered proteins within viscoelastic membraneless droplets
Fuga Watanabe, Takuma Akimoto, Robert B. Best +3
In living cells, intrinsically disordered proteins (IDPs), such as FUS and DDX4, undergo phase separation, forming biomolecular condensates. Using molecular dynamics simulations, w…
Statistics of the number of renewals, occupation times and correlation in ordinary, equilibrium and aging alternating renewal processes
Takuma Akimoto
Renewal process is a point process where an inter-event time between successive renewals is an independent and identically distributed random variable. Alternating renewal process…
