Asymmetric enzyme kinetics of F1-ATPase induced by rotation-assisted substrate binding
Yohei Nakayama, Shoichi Toyabe
We demonstrate asymmetric enzyme kinetics of a biomolecular motor F1-ATPase between synthesis and hydrolysis of adenosine triphosphate (ATP). Our experiments show that ATP hydrolys…
Effective Langevin equations leading to large deviation function of time-averaged velocity for a nonequilibrium Rayleigh piston
Masato Itami, Yohei Nakayama, Naoko Nakagawa +1
We study fluctuating dynamics of a freely movable piston that separates an infinite cylinder into two regions filled with ideal gas particles at the same pressure but different tem…
Optimal rectification without forward-current suppression by biological molecular motor
Yohei Nakayama, Shoichi Toyabe
We experimentally showed that biological molecular motor F-ATPase (F) implements an optimal rectification mechanism. F hardly suppresses adenosine triphosphate (ATP) sy…
Stochastic order parameter dynamics for phase coexistence in heat conduction
Shin-ichi Sasa, Naoko Nakagawa, Masato Itami +1
We propose a stochastic order parameter equation for describing phase coexistence in steady heat conduction near equilibrium. By analyzing the stochastic dynamics with a non-equili…
Multiplicative Langevin Equation to Reproduce Long-time Properties of Nonequilibrium Brownian Motion
Atsumasa Seya, Tatsuya Aoyagi, Masato Itami +2
We statistically examine long time sequences of Brownian motion for a nonequilibrium version of the Rayleigh piston model and confirm that the third cumulant of a long-time displac…
The Entropy Anomaly and the Linear Irreversible Thermodynamics
Kunimasa Miyazaki, Yohei Nakayama, Hiromichi Matsuyama
The irreversible currents and entropy production rate of a dilute colloidal suspension are calculated using the linear irreversible thermodynamics and the linear response theory. T…
Unattainability of Carnot efficiency in thermal motors: Coarse-graining and entropy production of Feynman-Smoluchowski ratchet
Yohei Nakayama, Kyogo Kawaguchi, Naoko Nakagawa
We revisit and analyze the thermodynamic efficiency of the Feynman-Smoluchowski (FS) ratchet, a classical thought experiment describing an autonomous heat-work converter. Starting…
Invariance of Steady State Thermodynamics between Different Scales of Description
Yohei Nakayama, Kyogo Kawaguchi
By considering general Markov stochastic dynamics and its coarse-graining, we study the framework of stochastic thermodynamics for the original and reduced descriptions correspondi…
Fluctuation Theorem for Hidden Entropy Production
Kyogo Kawaguchi, Yohei Nakayama
In the general process of eliminating dynamic variables in Markovian models, there exists a difference in the irreversible entropy production between the original and reduced dynam…
