The physical principles underlying pattern formation in biological cellular membranes are still not fully understood. To identify the minimal physical ingredients that a cellular membrane can use to regulate its patterns, we model it as a surface. We discover that only by considering matter exchange between this surface and its bulk environment, a complex patterned composition emerges. We show that typical domain length scales depend on the matter exchange rates. Bio-inspired, with applications well beyond it. An amazing collaboration between myself, Karsten Kruse, and Thierry Giamarchi.

New preprint

Microscopic interplay of temperature and disorder of a 1D elastic interface, by N. Caballero et al

We numerically unveil a new power law that emerges at intermediate scales above the thermal regime and below the KPZ one. We show that its exponent is below 1, contrarily to available analytical predictions.
