Many cell functions require a concerted effort from multiple membrane proteins, for example, for signaling, cell division, and endocytosis. One contribution to their successful self-organization stems from the membrane deformations that…
We use a two-dimensional (2D) elastic free energy to calculate the effective interaction between two circular disks immersed in smectic-$C$ films. For strong homeotropic anchoring, the distortion of the director field caused by the disks…
Recent theories predict that when a supercooled liquid approaches the glass transition, particle clusters with a special "amorphous order" nucleate within the liquid, which lead to static correlations dictating the dramatic slowdown of…
