Red blood cells, or erythrocytes, are seen to flicker under optical microscopy, a
phenomenon initially described as thermal fluctuations of the cell membrane. But recent …

Biological membranes constitute boundaries of cells and cell organelles. These membranes
are soft fluid interfaces whose thermodynamic states are dictated by bending moduli …

At the micron scale, where cell organelles display an amazing complexity in their shape and
organization, the physical properties of a biological membrane can be better-understood …

The cell nucleus is enveloped by a complex membrane, whose wrinkling has been
implicated in disease and cellular aging. The biophysical dynamics and spectral evolution of …

An important open problem in materials science is whether a direct connection exists
between single-particle elastic properties and macroscopic bulk behavior. Here, we address …

The buckling of thin elastic sheets is a classic mechanical instability that occurs over a wide
range of scales. In the extreme limit of atomically thin membranes like graphene, thermal …

Odd elasticity describes active elastic systems whose stress-strain relationship is not
compatible with a potential energy. As the requirement of energy conservation is lifted from …

We study a Brownian dynamics simulation model of a biopolymeric shell deformed by axial
forces exerted at opposing poles. The model exhibits two distinct, linear force-extension …

Steady progress in the miniaturization of structures and devices has reached a scale where
thermal fluctuations become relevant and it is thus important to understand how such …

We explore how thermal fluctuations affect the mechanics of thin amorphous spherical
shells. In flat membranes with a shear modulus, thermal fluctuations increase the bending …
