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…
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…
Generalized free energy and excess/housekeeping decomposition in nonequilibrium systems: from large deviations to thermodynamic speed limits
Artemy Kolchinsky, Andreas Dechant, Kohei Yoshimura +1
In genuine nonequilibrium systems that undergo continuous driving, the thermodynamic forces are nonconservative, meaning they cannot be described by any free energy potential. None…
Thermodynamic Geometric Constraint on the Spectrum of Markov Rate Matrices
Guo-Hua Xu, Artemy Kolchinsky, Jean-Charles Delvenne +1
The spectrum of Markov generators encodes physical information beyond simple decay and oscillation, which reflects irreversibility and governs the structure of correlation function…
Precision and cost of feedback cooling
Andreas Dechant, Jakob Hüpfl, Shuta Kobayashi +2
We investigate the consequences of information exchange between a system and a measurement-feedback apparatus that cools the system below the environmental temperature. A quantitat…
