We study the motion of a grain boundary that separates two sets of mutually perpendicular rolls in Rayleigh-Bénard convection above onset. The problem is treated either analytically from the corresponding amplitude equations, or numerically by solving the Swift-Hohenberg equation. We find that if the rolls are curved by a slow transversal modulation, a net translation of the boundary follows. We show analytically that although this motion is a nonlinear effect, it occurs in a time scale much…

TLDR
An algorithm for finding and identifying the disordering defects (dislocations, disclinations, and grain boundaries) at a given time is introduced and the system has a very low density of disclinations compared to that for dislocations and fraction of points in grain boundaries.

TLDR
Two-dimensional (2D) colloids embedded in a soap film are employed to study the structures and dynamics of grain boundaries, finding that the GB lines are faceted at "atomic" scale, leading to a constant energy per unit length along each line.
Anisotropic Linear Response in Block Copolymer Lamellar Phases
We examine the linear response of a lamellar block copolymer phase in the weak segregation regime and focus on those effects that arise from the uniaxial symmetry of the phase. The classical two
Structure-rheology relationship in a sheared lamellar fluid.
TLDR
The lattice Boltzmann method is used to solve the concentration and momentum equations for a two dimensional system of moderate size and for a low Reynolds number, and the other parameters are systematically varied to examine the qualitative features of the structure and viscosity evolution in different regimes.
Defect dynamics in mesophases
Block copolymer phases are a fertile ground in which to investigate both equilibrium and nonequilibrium properties of mesophases (phases that exhibit partial broken symmetries, intermediate between a

TLDR
A model for describing the defected growth of striped patterns that generates a quite different mixture of defects during phase ordering and finds two characteristic lengths in the system: the scaling length L(t), and the average width of the domain walls.
