thermodynamics via the configurational entropy and is of fundamental importance in …

Controlled neighbor exchanges drive glassy behavior, intermittency, and cell streaming in epithelial tissues

A Das, S Sastry, D Bi - Physical Review X, 2021 - APS
Cell neighbor exchanges are integral to tissue rearrangements in biology, including
development and repair. Often, these processes occur via topological T1 transitions …

Determination of onset temperature from the entropy for fragile to strong liquids

A Banerjee, MK Nandi, S Sastry… - The Journal of …, 2017 - pubs.aip.org

Structures and dynamics of glass-forming colloidal liquids under spherical confinement

B Zhang, X Cheng - Physical review letters, 2016 - APS
Recent theories predict that when a supercooled liquid approaches the glass transition,
particle clusters with a special “amorphous order” nucleate within the liquid, which lead to …

Interpretation of the apparent activation energy of glass transition

K Shirai - Journal of Physics Communications, 2021 - iopscience.iop.org
The temperature dependence of the viscosity of glass is a major concern in glass research.
The apparent activation energies obtained from Arrhenius plots often show unusual values …

The Adam–Gibbs relation and the TIP4P/2005 model of water

PH Handle, F Sciortino - Molecular physics, 2018 - Taylor & Francis
We report a numerical test of the Adam–Gibbs relation for the TIP4P/2005 model of water.
The configurational entropy is here evaluated as the logarithm of the number of different …
