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…
Inverse thermodynamic uncertainty relation and entropy production
Van Tuan Vo, Andreas Dechant, Keiji Saito
Nonequilibrium current fluctuations represent one of the central topics in nonequilibrium physics. The thermodynamic uncertainty relation (TUR) is widely acclaimed for rigorously e…
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…
Learning rate matrix and information-thermodynamic trade-off relation
Kenshin Matsumoto, Shin-ichi Sasa, Andreas Dechant
Non-equilibrium systems exchange information in addition to energy. In information thermodynamics, the information flow is characterized by the learning rate, which is not invarian…
