Analysis of hydrodynamic fluctuations in heterogeneous adjacent multidomains in shear flow

Journal Article Bian, Xin ; Deng, Mingge ; Tang, Yu-Hang ; ... - Physical Review E

We analyze hydrodynamic fluctuations of a hybrid simulation under shear flow. The hybrid simulation is based on the Navier-Stokes (NS) equations on one domain and dissipative particle dynamics (DPD) on the other. The two domains overlap, and there is an artificial boundary for each one within the overlapping region. To impose the artificial boundary of the NS solver, a simple spatial-temporal averaging is performed on the DPD simulation. In the artificial boundary of the particle simulation, four popular strategies of constraint dynamics are implemented, namely the Maxwell buffer [Hadjiconstantinou and Patera, Int. J. Mod. Phys. C 08, 967 (1997)], themore »« less

Nonaffine heterogeneities and droplet fluctuations in an equilibrium crystalline solid

Journal Article Das, Tamoghna ; Sengupta, Surajit ; Advanced Materials Research Unit, S. N. Bose National Centre for Basic Sciences, Salt Lake, Kolkata 700091 ; ... - Physical Review. E, Statistical, Nonlinear, and Soft Matter Physics (Print)

We show, using molecular-dynamics simulations, that a two-dimensional Lennard-Jones solid exhibits droplet fluctuations characterized by nonaffine deviations from local crystallinity. The fraction of particles in these droplets increases as the mean density of the solid decreases and approaches {approx_equal}20% of the total number in the vicinity of the fluid-solid phase boundary. We monitor the geometry, local equation of state, density correlations, and Van Hove functions of these droplets. We provide evidence that these nonaffine heterogeneities should be interpreted as being droplet fluctuations from nearby metastable minima. The local excess pressure of the droplets plotted against the local number density showsmore »« less

Harvesting thermal fluctuations: Activation process induced by a nonlinear chain in thermal equilibrium

Journal Article Reigada, Ramon ; Sarmiento, Antonio ; Romero, Aldo H ; ... - Journal of Chemical Physics

We present a model in which the immediate environment of a bistable system is a molecular chain which in turn is connected to a thermal environment of the Langevin form. The molecular chain consists of masses connected by harmonic or by anharmonic springs. The distribution, intensity, and mobility of thermal fluctuations in these chains is strongly dependent on the nature of the springs and leads to different transition dynamics for the activated process. Thus, all else (temperature, damping, coupling parameters between the chain and the bistable system) being the same, the hard chain may provide an environment described as diffusion-limitedmore »« less

Thermally induced hydrodynamic fluctuations below the onset of electroconvection

Journal Article Rehberg, I ; Rasenat, S ; de la Torre Juarez, M. ; ... - Physical Review Letters; (United States)

Measurements of the correlation function below the electrohydrodynamic instability in a thin layer of a nematic liquid crystal reveal fluctuating convection patches. Their amplitude {ital {bar A}}, correlation length {xi}, and correlation time {tau} can be desribed by a stochastic mean-field model. The amplitude agrees with the expected fluctuations due to thermal noise.
