The probability of trajectories of weakly diffusive processes to remain in the tubular neighborhood of a smooth path is given by the Freidlin-Wentzell-Graham theory of large deviations. The most probable path between two states (the instanton) and th

Interface roughening in nonequilibrium phase-separated systems

Autor: M. Besse, G. Fausti, M. E. Cates, B. Delamotte, C. Nardini

Interfaces of phase-separated systems roughen in time due to capillary waves. Because of fluxes in the bulk, their dynamics is nonlocal in real space and is not described by the Edwards-Wilkinson or Kardar-Parisi-Zhang (KPZ) equations, nor their cons

RANDOM SURFACTANT ASSEMBLIES AND MICROEMULSIONS

Autor: M. E. Cates

Publikováno v: Phase Transitions in Soft Condensed Matter ISBN: 9781461278627

Surfactant molecules in dilute solution have a strong tendency to aggregate reversibly into larger structures1. While this often involves the formation of simple, roughly spherical micelles, there is now strong experimental and industrial interest in

By molecular-dynamics simulations, we have studied the devitrification (or crystallization) of aged hard-sphere glasses. First, we find that the dynamics of the particles are intermittent: Quiescent periods, when the particles simply "rattle" in thei

Deformation of Polyelectrolyte Brushes in Strong Flows: Good Solvent Regime

Autor: J. L. Harden, O. V. Borisov, M. E. Cates

Publikováno v: Macromolecules. 30:1179-1187

We study theoretically the deformation of polyelectrolyte brushes in strong flows of good solvent using a scaling theory which calculates the deformation of grafted chains and the solvent flow profile within the brush in a mutually consistent fashion
