Spontaneous flow created by active topological defects
Louis Brézin, Thomas Risler, Jean-François Joanny
Topological defects are at the root of the large-scale organization of liquid crystals. In two-dimensional active nematics, two classes of topological defects of charges …
Viscocapillary Instability in Cellular Spheroids
Matthieu Martin, Thomas Risler
We describe a viscocapillary instability that can perturb the spherical symmetry of cellular aggregates in culture, also called multicellular spheroids. In the condition where the…
Lipid bilayer mediates ion-channel cooperativity in a model of hair-cell mechanotransduction
Francesco Gianoli, Thomas Risler, Andrei S. Kozlov
Mechanoelectrical transduction in the inner ear is a biophysical process underlying the senses of hearing and balance. The key players involved in this process are mechanosensitive…
Homeostatic Fluctuations of a Tissue Surface
Thomas Risler, Aurélien Peilloux, Jacques Prost
We study the surface fluctuations of a tissue with a dynamics dictated by cell-rearrangement, cell-division, and cell-death processes. Surface fluctuations are calculated in the ho…
Focus on the Physics of Cancer
Thomas Risler
Despite the spectacular achievements of molecular biology in the second half of the twentieth century and the crucial advances it permitted in cancer research, the fight against ca…
Damping Properties of the Hair Bundle
Johannes Baumgart, Andrei S. Kozlov, Thomas Risler +1
The viscous liquid surrounding a hair bundle dissipates energy and dampens oscillations, which poses a fundamental physical challenge to the high sensitivity and sharp frequency se…
