Molecular dynamics computer simulations of a polydisperse soft-sphere model under shear
are presented. The starting point for these simulations are deeply supercooled samples far …

Customarily, crystalline solids are defined to be rigid since they resist changes of shape
determined by their boundaries. However, rigid solids cannot exist in the thermodynamic …

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 …

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 …

Thermal displacement fluctuations in a crystal may be classified as either “affine” or “non-
affine”. While the former couples to external stress with familiar consequences, the response …

We show that a flat two dimensional network of connected vertices, when stretched, may
deform plastically by producing “pleats”, system spanning linear structures with width …

We show that dynamic, feed-back controlled optical traps, whose positions depend on the
instantaneous local configuration of particles in a pre-determined way, can stabilise colloidal …

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 …
