Active Contact Forces Drive Non-Equilibrium Fluctuations in Membrane Vesicles
Sho C. Takatori, Amaresh Sahu
We analyze the non-equilibrium shape fluctuations of giant unilamellar vesicles encapsulating motile bacteria. Owing to bacteria--membrane collisions, we experimentally observe a s…

Arbitrary Lagrangian--Eulerian finite element method for curved and deforming surfaces. I. General theory and application to fluid interfaces
Amaresh Sahu, Yannick A. D. Omar, Roger A. Sauer +1
An arbitrary Lagrangian--Eulerian (ALE) finite element method for arbitrarily curved and deforming two-dimensional materials and interfaces is presented here. An ALE theory is deve…
