Hierarchy of entropy production and thermodynamic trade-off relations in non-Markovian systems

Ken Funo, Tan Van Vu, Keiji Saito

Non-Markovian dynamics arise when a system is coupled to a bath with finite correlation time, producing memory effects that allow the bath to temporarily store and return excitatio…

Universal criticality of entropy production in chemical reaction networks

Kyota Tamano, Keiji Saito

Stochastic thermodynamics gives universal relations for microscopic entropy production, yet its critical behavior at macroscopic nonequilibrium transitions remains unclassified. We…

Inverse thermodynamic uncertainty relation and entropy production

Van Tuan Vo, Andreas Dechant, Keiji Saito

Nonequilibrium current fluctuations represent one of the central topics in nonequilibrium physics. The thermodynamic uncertainty relation (TUR) is widely acclaimed for rigorously e…

Thermodynamic Uncertainty Relations for Coherent Transport

Kay Brandner, Keiji Saito

We derive a universal thermodynamic uncertainty relation for Fermionic coherent transport, which bounds the total rate of entropy production in terms of the mean and fluctuations o…

Energy diffusion in the long-range interacting spin systems

Hideaki Nishikawa, Keiji Saito

We investigate energy diffusion in long-range interacting spin systems, where the interaction decays algebraically as with the distance between the sites…

Thermodynamic bound on current fluctuations in coherent conductors

Kay Brandner, Keiji Saito

We derive a universal bound on the large-deviation functions of particle currents in coherent conductors. This bound depends only on the mean value of the relevant current and the…
