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…
Interplay between Standard Quantum Detailed Balance and Thermodynamically Consistent Entropy Production
Xin-Hai Tong, Kohei Yoshimura, Tan Van Vu +1
We demonstrate that, for a quantum Markovian semigroup on a finite-dimensional Hilbert space, if it satisfies the standard quantum detailed balance condition, its generator admits…
Quasiprobability Thermodynamic Uncertainty Relation
Kohei Yoshimura, Ryusuke Hamazaki
We derive a quantum extension of the thermodynamic uncertainty relation where dynamical fluctuations are quantified by the Terletsky-Margenau-Hill quasiprobability, a quantum gener…
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…
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…
