Determining Critical Temperature Differences of Low-Temperature-Differential Stirling Engines: Nonlinear Dynamics Approach
Momoko Amemiya, Yuki Izumida
The paper uses nonlinear dynamics to derive self‑consistent equations that identify the critical temperature difference at which low‑temperature‑differential Stirling engines stop…
Mean-Field Theory for Heider Balance under Heterogeneous Social Temperatures
Zhen Li, Yuki Izumida
Heider balance theory provides a fundamental framework for understanding the formation of friendly and hostile relations in social networks. Existing stochastic formulations typica…
Irreversibility of the pendulum revisited from Husimi's adiabaticity parameter
Yuki Izumida
We revisit the irreversibility of the pendulum with time-dependent angular frequency, considered in a classical paper by K. Husimi. He introduced a parameter that measures the adia…
Formulation of Entropy through Work by Carnot Machine and Direct Derivation of Law of Entropy Non-Decrease from Kelvin-Planck Principle
Yuki Izumida
We derive the law of entropy non-decrease directly from the Kelvin-Planck principle for simple and compound systems without using the Clausius inequality. A key of the derivation i…
Nonlinear refrigerator with a finite-sized cold heat bath
I. Iyyappan, Yuki Izumida, Sibasish Ghosh
We study the refrigerator working between a finite-sized cold heat bath and an infinite-sized hot heat bath (environment) in the nonlinear response regime. We assume that the initi…
Nonequilibrium thermodynamics of populations of weakly-coupled low-temperature-differential Stirling engines with synchronous and asynchronous transitions
Songhao Yin, Hiroshi Kori, Yuki Izumida
This study developed the theory of nonequilibrium thermodynamics for populations of low-temperature-differential (LTD) Stirling engines weakly-coupled in a general class of network…
