Derivation of the nonlinear fluctuating hydrodynamic equation from underdamped Langevin equation
, 2008 We derive the fluctuating hydrodynamic equation for the number and momentum densities exactly from the underdamped Langevin equation. This derivation is an extension of the Kawasaki-Dean formula in underdamped case.
