Unified geometric formalism for dissipation and its fluctuations in finite-time microscopic heat engines
Gentaro Watanabe, Guo-Hua Xu, Yuki Minami
Microscopic heat engines operate in regimes where thermodynamic quantities fluctuate strongly, making stochastic effects an essential aspect of their performance. However, existing…
Quantitative analysis of fluctuating hydrodynamics in uniform shear flow
Hiroyoshi Nakano, Yuki Minami
Many theoretical predictions in fluctuating hydrodynamics under uniform shear flow have lacked precise quantitative verification because assessing the impact of analytical approxim…
Dissipation anomaly in gradient-driven nonequilibrium steady states
Hiroyoshi Nakano, Yuki Minami
Dissipation anomaly-the persistence of finite energy dissipation in the inviscid limit-is a hallmark of turbulence, sometimes regarded as the "zeroth law" of turbulent flows. Here,…
Symmetry-based nonlinear fluctuating hydrodynamics in one dimension
Yuki Minami, Hiroyoshi Nakano, Keiji Saito
We present a symmetry-based formulation of nonlinear fluctuating hydrodynamics (NFH) for one-dimensional many-particle systems with generic homogeneous nearest-neighbor interaction…
Looking at bare transport coefficients in fluctuating hydrodynamics
Hiroyoshi Nakano, Yuki Minami, Keiji Saito
Bare transport coefficients in fluctuating hydrodynamics are not directly observable in bulk systems, as hydrodynamic fluctuations inevitably renormalize them into macroscopic valu…
