Second-order hydrodynamics for fermionic cold atoms: Detailed analysis of transport coefficients and relaxation times
Yuta Kikuchi, Kyosuke Tsumura, Teiji Kunihiro
We give a detailed derivation of the second-order (local) hydrodynamics for Boltzmann equation with an external force by using the renormalization group method. In this method, we…
Mesoscopic dynamics of fermionic cold atoms ---Quantitative analysis of transport coefficients and relaxation times---
Yuta Kikuchi, Kyosuke Tsumura, Teiji Kunihiro
We give a quantitative analysis of the dynamical properties of fermionic cold atomic gases in normal phase, such as the shear viscosity, heat conductivity, and viscous relaxation t…
Derivation of second-order relativistic hydrodynamics for reactive multi-component systems
Yuta Kikuchi, Kyosuke Tsumura, Teiji Kunihiro
We derive the second-order hydrodynamic equation for reactive multi-component systems from the relativistic Boltzmann equation. In the reactive system, particles can change their s…
Relativistic Causal Hydrodynamics Derived from Boltzmann Equation: a novel reduction theoretical approach
Kyosuke Tsumura, Yuta Kikuchi, Teiji Kunihiro
We derive the second-order hydrodynamic equation and the microscopic formulae of the relaxation times as well as the transport coefficients systematically from the relativistic Bol…
Rare transition event with self-consistent theory of large-amplitude collective motion
Kyosuke Tsumura, Yoshitaka Maeda, Hiroyuki Watanabe
A numerical simulation method, based on Dang et al.'s self-consistent theory of large-amplitude collective motion, for rare transition events is presented. The method provides a on…
Causal hydrodynamics from kinetic theory by doublet scheme in renormalization-group method
Kyosuke Tsumura, Yuta Kikuchi, Teiji Kunihiro
We develop a general framework in the renormalization-group (RG) method for extracting a mesoscopic dynamics from an evolution equation by incorporating some excited (fast) modes a…
