Arbitrary Amplification of Quantum Coherence in Asymptotic and Catalytic Transformation

Naoto Shiraishi, Ryuji Takagi

Quantum coherence is one of the fundamental aspects distinguishing classical and quantum theories. Coherence between different energy eigenstates is particularly important, as it s…

Proof of avoidability of the quantum first-order transition in transverse magnetization in quantum annealing of finite-dimensional spin glasses

Mizuki Sanatani, Naoto Shiraishi, Koji Hukushima

It is rigorously shown that an appropriate quantum annealing for any finite-dimensional spin system has no quantum first-order transition in transverse magnetization. This result c…

Entropy production limits all fluctuation oscillations

Naoto Shiraishi

The oscillation of fluctuation with two state observables is investigated. Following the idea of Ohga, et al. [arXiv:2303.13116], we find that the fluctuation oscillation relative…

Fluctuation-response relation of time-symmetric quantities around general nonequilibrium stationary state

Naoto Shiraishi

A connection between the response and fluctuation in general nonequilibrium stationary states is investigated. We focus on time-symmetric quantities and find that the fluctuation o…

Is there any upper bound on current fluctuation in cross-transport beyond linear response regime?

Naoto Shiraishi, Tan Van Vu, Keiji Saito

Input and output current fluctuations in stationary cross-transport systems with two kinds of currents are investigated. In Saryal {\it et al.} [Phys. Rev. Lett. 127, 190603 (2021)…

Time-symmetric current and its fluctuation response relation around nonequilibrium stalling stationary state

Naoto Shiraishi

We propose a time-symmetric counterpart of the current in stochastic thermodynamics named time-symmetric current. This quantity is defined with empirical measures and thus is symme…
