Spurious diffusion in particle simulations of the Kolmogorov flow
M. Malek Mansour, C. Van den Broeck, I. Bena +1
Particle simulations of the Kolmogorov flow are analyzed by the Landau-Lifshitz fluctuating hydrodynamics. It is shown that a spurious diffusion of the center of mass corrupts the…
Velocity Correlations, Diffusion and Stochasticity in a One-Dimensional System
V. Balakrishnan, I. Bena, C. Van den Broeck
We consider the motion of a test particle in a one-dimensional system of equal-mass point particles. The test particle plays the role of a microscopic "piston" that separates two h…
Parametric phase transition in one dimension
J. Farago, C. Van den Broeck
We calculate analytically the phase boundary for a nonequilibrium phase transition in a one-dimensional array of coupled, overdamped parametric harmonic oscillators in the limit of…
On the Collective Behavior of Parametric Oscillators
I. Bena, R. Kawai, C. Van den Broeck +2
We revisit the mean field model of globally and harmonically coupled parametric oscillators subject to periodic block pulses with initially random phases. The phase diagram of regi…
