Brownian Motion in a Classical Ideal Gas: a Microscopic Approach to Langevin's Equation
Rangan Lahiri, Arvind, Anirban Sain
We present an insightful ``derivation'' of the Langevin equation and the fluctuation dissipation theorem in the specific context of a heavier particle moving through an ideal gas o…

Temporal correlation function in 3-D Turbulence
Anirban Sain
We observe oscillatory decay in the two-point, non-equal time, velocity correlation function of homogeneous, isotropic turbulence. We found this through a direct numerical simulati…
