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…

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…
