Oscillatory-nonnormal decomposition of dissipation in Ornstein-Uhlenbeck processes
Ryuna Nagayama, Artemy Kolchinsky, Sosuke Ito
We provide a decomposition of the steady-state entropy production rate associated with an Ornstein-Uhlenbeck process into two contributions: one associated with oscillatory behavio…
Geometric decomposition of information flow: New insights into information thermodynamics
Yoh Maekawa, Ryuna Nagayama, Kohei Yoshimura +1
We propose a decomposition of information flow into housekeeping and excess components for autonomous bipartite systems described by Markov jump processes. We introduce this decomp…
Duality between dissipation-coherence trade-off and thermodynamic speed limit based on thermodynamic uncertainty relation for stochastic limit cycles
Ryuna Nagayama, Sosuke Ito
We derive two fundamental trade-offs for general stochastic limit cycles in the weak-noise limit. The first is the dissipation-coherence trade-off, which was discovered and proved…
Diagrammatic expressions for steady-state distribution and static responses in population dynamics
Koya Katayama, Ryuna Nagayama, Sosuke Ito
One of the fundamental questions in population dynamics is how biological populations respond to environmental perturbations. In population dynamics, the mean fitness and the fract…
Geometric decomposition of information flow for overdamped Langevin systems and optimal transport in subsystems
Sosuke Ito, Yoh Maekawa, Ryuna Nagayama +2
Information flow between subsystems is a central concept in information thermodynamics, which provides the second-law-like inequalities for subsystems. This paper discusses the geo…
Infinite variety of thermodynamic speed limits with general activities
Ryuna Nagayama, Kohei Yoshimura, Sosuke Ito
Activity, which represents the kinetic property of dynamics, plays a central role in obtaining thermodynamic speed limits (TSLs). In this paper, we discuss a unified framework that…
