Weak-inertial flow between two rough surfaces [PDF]
, 2005 “Oseen–Poiseuille” equations are developed from an asymptotic formulation of the three-dimensional Navier–Stokes equations in order to study the influence of weak inertia on flows between rough surfaces.

A simple model for heterogeneous flows of yield stress fluids
, 2002 Various experiments evidence spatial heterogeneities in sheared yield stress fluids. To account for heterogeneities in the velocity gradient direction, we use a simple model corresponding to a non-monotonous local constitutive curve and study a simple ...

Studying Social Networks at Scale: Macroscopic Anatomy of the Twitter Social Graph [PDF]
, 2014 Twitter is one of the largest social networks using exclusively directed links among accounts. This makes the Twitter social graph much closer to the social graph supporting real life communications than, for instance, Facebook.

The Mirrors Model : Macroscopic Diffusion Without Noise or Chaos [PDF]
, 2015 We first clarify through classical examples the status of the laws of macroscopic physics as laws of large numbers. We next consider the mirrors model in a finite $d$-dimensional domain and connected to particles reservoirs at fixed chemical potentials ...

A Method to Study Relaxation of Metastable Phases: Macroscopic Mean-Field Dynamics
, 1995 We propose two different macroscopic dynamics to describe the decay of metastable phases in many-particle systems with local interactions. These dynamics depend on the macroscopic order parameter $m$ through the restricted free energy $F(m)$ and are ...

Macroscopic Many-Qubit Interactions in Superconducting Flux Qubits [PDF]
, 2007 Superconducting flux qubits are considered to investigate macroscopic many-qubit interactions. Many-qubit states based on current states can be manipulated through the current-phase relation in each superconducting loop.

Hund's rule and metallic ferromagnetism
, 2004 We study tight-binding models of itinerant electrons in two different bands, with effective on-site interactions expressing Coulomb repulsion and Hund's rule.

Quantum tunneling of magnetization in dipolar spin-1 condensates under external fields
, 2006 We study the macroscopic quantum tunneling of magnetization of the F=1 spinor condensate interacting through dipole-dipole interaction with an external magnetic field applied along the longitudinal or transverse direction.

The dynamics of critical fluctuations in asymmetric Curie-Weiss models
, 2017 We study the dynamics of fluctuations at the critical point for two time-asymmetric version of the Curie-Weiss model for spin systems that, in the macroscopic limit, undergo a Hopf bifurcation.

Macroscopic Time-Reversal Symmetry Breaking at Nonequilibrium Phase Transition
, 2015 We study the entropy production in a macroscopic nonequilibrium system that undergoes an order-disorder phase transition. Entropy production is a characteristic feature of nonequilibrium dynamics with broken detailed balance. It is found that the entropy
