Unconventional Growth Kinetics and Fractal Interfaces of Colloidal Phase Separation in Active Liquids
Pragya Kushwaha, Pratikshya Jena, Partha Sarathi Mondal +4
Phase separation driven by nonequilibrium fluctuations is a hallmark of both living and synthetic active matter. Unlike equilibrium systems, where ordered states arise from the min…
The Physics of Topological Defects in Glasses
Arabinda Bera, Peter Schall, Timothy W. Sirk +2
Topological defects play a central role in the mechanical behavior of crystalline materials, yet their relevance to amorphous solids has only recently begun to emerge. Over the las…
Modulating hydrodynamic flow by modifying the active patch of a colloid
Om Vandra, Suhal Siva Ratan T. N., Hemant Giri +4
We have developed a simulation model to study the hydrodynamic flow fields around Brownian colloidal particles with an active surface patch. Hydrodynamics is introduced by modeling…
Shear induced topological changes of local structure in dense colloidal suspensions
Ratimanasee Sahu, Abhishek Kumar Gupta, Peter Schall +2
Understanding the structural origins of glass formation and mechanical response remains a central challenge in condensed matter physics. Recent studies have identified the local ca…
