On the existence of thermodynamically stable rigid solids
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 …

Traveling band formation in feedback-driven colloids
Using simulation and theory we study the dynamics of a colloidal suspension in two
dimensions subject to a time-delayed repulsive feedback that depends on the positions of …

Exploring the link between crystal defects and nonaffine displacement fluctuations
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 …

Pattern stabilization in swarms of programmable active matter: A probe for turbulence at large length scales
P Popli, P Perlekar, S Sengupta - Physical Review E, 2021 - APS
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 …

Wrinkles, folds, and ripplocations: Unusual deformation structures of confined elastic sheets at nonzero temperatures
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 …
