Higher-order Efficiency Bound and Its Application to Nonlinear Nano-thermoelectrics

no code implementations11 Mar 2021 Takuya Kamijima, Shun Otsubo, Yuto Ashida, Takahiro Sagawa

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 tradeoff.

Topological synchronization of coupled nonlinear oscillators

no code implementations17 Dec 2020 Kazuki Sone, Yuto Ashida, Takahiro Sagawa

The topological synchronization can ubiquitously appear in topological nonlinear oscillators and thus can provide a guiding principle to realize synchronization in a robust, geometrical, and flexible way.

Deep Reinforcement Learning Control of Quantum Cartpoles

1 code implementation21 Oct 2019 Zhikang T. Wang, Yuto Ashida, Masahito Ueda

We generalize a standard benchmark of reinforcement learning, the classical cartpole balancing problem, to the quantum regime by stabilizing a particle in an unstable potential through measurement and feedback.
