Experiments and simulations show that when an initially defect-free rigid crystal is subjected
to deformation at a constant rate, irreversible plastic flow commences at the so-called yield …

Recent work suggests that layered solids deform through buckling of basal planes. When
isolated locally, as in graphite, these buckles, termed ripplocations, behave superficially …

We generalize and then use a recently introduced formalism to study thermal fluctuations of
atomic displacements in several two-and three-dimensional crystals. We study both close …

Identifying subtle conformational fluctuations underlying the dynamics of biomacromolecules
is crucial for resolving their free energy landscape. We show that a collective variable …

Starting from an ideal crystalline state, we numerically study a nonequilibrium dynamical
order–disorder transition promoted by the application of a periodic shearing protocol at low …

We propose an algorithm for creating stable, ordered, swarms of active robotic agents
arranged in any given pattern. The strategy involves suppressing a class of fluctuations …

We study the deformation of a fluctuating crystalline sheet confined between two flat rigid
walls as a simple model for layered solids where bonds among atoms within the same layer …

Cells are the basic units of all living organisms. Eukaryotic cells are stuctured on top of a
scaffold of fibers ranging from stiff microtubules to semiflexible actin: the cytoskeleton. As …
