Higher-order Efficiency Bound and Its Application to Nonlinear Nano-thermoelectrics
Takuya Kamijima, Shun Otsubo, Yuto Ashida +1
Power and efficiency of heat engines are two conflicting objectives, and a tight efficiency bound is expected to give insights on the fundamental properties of the power-efficiency…

Estimating entropy production by machine learning of short-time fluctuating currents
Shun Otsubo, Sosuke Ito, Andreas Dechant +1
Thermodynamic uncertainty relations (TURs) are the inequalities which give lower bounds on the entropy production rate using only the mean and the variance of fluctuating currents.…

Information-thermodynamic characterization of stochastic Boolean networks
Shun Otsubo, Takahiro Sagawa
Recent progress in experimental techniques has enabled us to quantitatively study stochastic and flexible behavior of biological systems. For example, gene regulatory networks perf…
