On the existence of thermodynamically stable rigid solids

P Nath, S Ganguly, J Horbach… - Proceedings of the …, 2018 - National Acad Sciences
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

S Tarama, SU Egelhaaf, H Löwen - Physical Review E, 2019 - APS
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

P Popli, S Kayal, P Sollich, S Sengupta - Physical Review E, 2019 - APS
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 …

Nonaffine displacements encode collective conformational fluctuations in proteins

DD Prakashchand, N Ahalawat… - Journal of Chemical …, 2020 - ACS Publications
Identifying subtle conformational fluctuations underlying the dynamics of biomacromolecules
is crucial for resolving their free energy landscape. We show that a collective variable …

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

D Das, J Horbach, P Sollich, T Saha-Dasgupta… - Physical Review …, 2020 - APS
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 …

Dynamic adaptive colloidal crystals far from equilibrium

R Ghaffari - 2019 - search.proquest.com
Self-assembly has been the center of attention of many researchers from all branches of
science. Self-assembly of static structures such as crystals often forms through energy …

[PDF][PDF] Colloidal suspensions responsive to external field variations

S Tarama - 2019 - d-nb.info
Colloidal suspensions are comprised of small solid particles suspended in a liquid. The
particles are mesoscopic in size, such that they are typically much larger than the …
