Spatial correlations of hydrodynamic fluctuations in simple fluids under shear flow: A mesoscale simulation study
Anoop Varghese, Gerhard Gompper, Roland G. Winkler
Hydrodynamic fluctuations in simple fluids under shear flow are demonstrated to be spatially correlated, in contrast to the fluctuations at equilibrium, using mesoscopic hydrodynam…
Time correlation functions in the Lebwohl-Lasher model of liquid crystals
Anoop Varghese, Patrick Ilg
Time correlation functions in the Lebwohl-Lasher model of nematic liquid crystals are studied using theory and molecular dynamics simulations. In particular, the autocorrelation fu…
Hydrodynamic correlations in shear flow: A Multiparticle--Collision--Dynamics simulation study
Anoop Varghese, Chien-Cheng Huang, Roland G. Winkler +1
The nonequilibrium hydrodynamic correlations of a Multiparticle-Collision-Dynamics (MPC) fluid in shear flow are studied by analytical calculations and simulations. The Navier-Stok…
Thermostat for non-equilibrium multiparticle collision dynamics simulations
Chien-Cheng Huang, Anoop Varghese, Gerhard Gompper +1
Multiparticle collision dynamics (MPC), a particle-based mesoscale simulation technique for com- plex fluid, is widely employed in non-equilibrium simulations of soft matter system…
Force fluctuations in stretching a tethered polymer
Anoop Varghese, Satyavani Vemparala, R. Rajesh
The recently proposed fluctuation relation in unfolding forces [Phys. Rev. E , (R) ] is re-examined taking into account the explicit time dependence of th…
Aggregation of rod-like polyelectrolyte chains in the presence of monovalent counterions
Anoop Varghese, R. Rajesh, Satyavani Vemparala
Using molecular dynamics simulations, it is demonstrated that monovalent counterions can induce aggregation of similarly charged rod-like polyelectrolyte chains. The critical value…
Ensemble Equivalence for Counterion Condensation on a Two Dimensional Charged Disc
Anoop Varghese, Satyavani Vemparala, R. Rajesh
We study the counterion condensation on a two dimensional charged disc in the limit of infinite dilution, and compare the energy-temperature relation obtained from the canonical fr…
Phase transitions of a single polyelectrolyte in a poor solvent with explicit counterions
Anoop Varghese, Satyavani Vemparala, R. Rajesh
Conformational properties of a single flexible polyelectrolyte chain in a poor solvent are studied using constant temperature molecular dynamics simulation. The effects of counteri…
