Flow boundary conditions from nano- to micro-scales
Lydéric Bocquet, J. -L. Barrat
The development of microfluidic devices has recently revived the interest in "old" problems associated with transport at, or across, interfaces. As the characteristic sizes are dec…
Modeling thermal conductivity and collective effects in a simple nanofluid
Mihail Vladkov, J. -L. Barrat
Molecular dynamics simulations are used to model the thermal properties of a fluid containing solid nanoparticles (nanofluid). The flexibility of molecular simulation allows us to…
Particle displacements in the elastic deformation of amorphous materials: local fluctuations vs. non-affine field
C. Goldenberg, A. Tanguy, J. -L. Barrat
We study the local disorder in the deformation of amorphous materials by decomposing the particle displacements into a continuous, inhomogeneous field and the corresponding fluctua…
Local dynamics and primitive path analysis for a model polymer melt near a surface
Mihail Vladkov, J. -L. Barrat
By applying local primitive path and Rouse modes analysis we study the chains conformations, local dynamics and viscosity of a model polymer melt in a polymer-wall interface. We es…
Plastic Response of a 2D Lennard-Jones amorphous solid: Detailed analysis of the local rearrangements at very slow strain-rate
Anne Tanguy, Fabien Leonforte, J. -L. Barrat
We analyze in details the atomistic response of a model amorphous material submitted to plastic shear in the athermal, quasistatic limit. After a linear stress-strain behavior, the…
Inhomogeneous elastic response of silica glass
Fabien Leonforte, Anne Tanguy, Joachim Wittmer +1
Using large scale molecular dynamics simulations we investigate the properties of the {\em non-affine} displacement field induced by macroscopic uniaxial deformation of amorphous s…
Modeling transient absorption and thermal conductivity in a simple nanofluid
Mihail Vladkov, J. -L. Barrat
Molecular dynamics simulations are used to simulate the thermal properties of a model fluid containing nanoparticles (nanofluid). By modelling transient absorption experiments, we…
Effective temperatures in a simple model of non-equilibrium, non-Markovian dynamics
Patrick Ilg, J. -L. Barrat
The concept of effective temperatures in nonequilibrium systems is studied within an exactly solvable model of non-Markovian diffusion. The system is coupled to two heat baths whic…
