Interacting self-phoretic particles on a ring
Leah Anderson, David S. Dean
We study the spontaneous motion and collective dynamics of self-phoretic particles on a ring. The particles act as localized sources of a chemical field, with particle-dependent so…
Dielectric response as a source of viscosity in polar liquids
David S. Dean, Haim Diamant
Transport coefficients and dielectric relaxation in liquids are often treated as distinct manifestations of molecular dynamics. We show that, in polar liquids, orientational dipola…
Self-phoretic oscillatory motion in a one-dimensional channel
Leah Anderson, David S. Dean
We study a simple model for a particle that is active due to self-phoresis and that has been proposed to model symmetric camphor grains. The particle generates a concentration fiel…
Solving Lyapunov equations for electrically driven ternary electrolytes -- application to long-range van der Waals interactions
Guangle Du, Bing Miao, David S. Dean
Stochastic density functional theory (SDFT) has been widely used to study the out of equilibrium properties of electrolyte solutions. Examples include investigations of electrical…
Effective description of Taylor dispersion in strongly corrugated channels
Arthur Alexandre, Thomas Guérin, David S. Dean
Taylor dispersion in periodic but highly corrugated channels is studied. Exact analytical expressions for the long-time diffusion constant and drift along the channel are derived t…
Repulsive thermal van der Waals interaction in multi-species asymmetric electrolytes driven by external electric fields
Guangle Du, David S. Dean, Bing Miao +1
It is well established that the long-range component of the thermal van der Waals interaction between two semi-infinite dielectrics becomes short-range when an electrolyte is prese…
Correlation decoupling of Casimir interaction in an electrolyte driven by external electric fields
Guangle Du, David S. Dean, Bing Miao +1
It has been established for a long time that the long range van der Waals or thermal Casimir interaction between two semi-infinite dielectrics separated by a distance is screen…
Self-phoretic oscillatory motion in a harmonic trap
A. Alexandre, L. Anderson, T. Collin-Dufresne +2
We consider the motion of a harmonically trapped overdamped particle, which is submitted to a self-phoretic force, that is proportional to the gradient of a diffusive field for whi…
Uphill drift in the absence of current in single-file diffusion
Benjamin Sorkin, David S. Dean
Single-file diffusion is a paradigmatic model for the transport of Brownian colloidal particles in narrow one-dimensional channels, such as those found in certain porous media, whe…
