Fluctuations of the Casimir-like force between two membrane inclusions
Anne-Florence Bitbol, Paul G. Dommersnes, Jean-Baptiste Fournier
Although Casimir forces are inseparable from their fluctuations, little is known about these fluctuations in soft matter systems. We use the membrane stress tensor to study the flu…
Osmotically Driven Shape Transformations in Axons
Pramod A. Pullarkat, Paul Dommersnes, Pablo Fernández +3
We report a cylindrical-peristaltic shape transformation in axons exposed to a controlled osmotic perturbation. The peristaltic shape relaxes and the axon recovers its original geo…
Tight and loose shapes in flat entangled dense polymers
Andreas Hanke, Ralf Metzler, Paul G. Dommersnes +2
We investigate the effects of topological constraints (entanglements) on two dimensional polymer loops in the dense phase, and at the collapse transition (Theta point). Previous st…
Dynamin recruitment by clathrin coats: a physical step?
J. -B. Fournier, P. -G. Dommersnes, P. Galatola
Recent structural findings have shown that dynamin, a cytosol protein playing a key-role in clathrin-mediated endocytosis, inserts partly within the lipid bilayer and tends to self…
Knots in Charged Polymers
Paul G. Dommersnes, Yacov Kantor, Mehran Kardar
The interplay of topological constraints and Coulomb interactions in static and dynamic properties of charged polymers is investigated by numerical simulations and scaling argument…
Equilibrium shapes of flat knots
Ralf Metzler, Andreas Hanke, Paul G. Dommersnes +2
We study the equilibrium shapes of prime and composite knots confined to two dimensions. Using rigorous scaling arguments we show that, due to self-avoiding effects, the topologica…
