Dynamical renormalization group analysis of model in steady shear flow
Harukuni Ikeda, Hiroyoshi Nakano
We study the critical behavior of the model under steady shear flow using a dynamical renormalization group (RG) method. Incorporating the strong anisotropy in scaling ansat…
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…
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,…
Looking at bare transport coefficients in fluctuating hydrodynamics
Hiroyoshi Nakano, Yuki Minami, Keiji Saito
Hydrodynamics at the macroscopic scale, composed of a vast ensemble of microscopic particles, is described by the Navier-Stokes equation. However, at the mesoscopic scale, bridging…
Spontaneous symmetry breaking in two dimensions under nonequilibrium laminar flows
Yuki Minami, Hiroyoshi Nakano
We study the long-range order in two dimensions where an order parameter is advected by laminar flows such as rotational, shear, and elongational flows. Under these flows, we analy…
