Two-Temperature Induced Phase Separation: Non-equilibrium Phase Behavior, Ordering, and Kinetics
Nayana Venkatareddy, Jaydeep Mandal, Jayeeta Chattopadhyay +1
Two-temperature induced phase separation (2-TIPS) has emerged as a generic non-equilibrium mechanism in scalar active systems with heterogeneous activity, where particles coupled t…
Density-Induced Reentrant Coarsening in a Two-Temperature System
Partha Sarathi Mondal, Anish Kumar, Nayana Venkatareddy +2
Understanding how nonequilibrium driving modifies phase-separation kinetics remains a fundamental challenge. Here we show that phase separation in a two-temperature system exhibits…
Ionic Liquid-Driven Modulation of DNA Brush Morphology on Nanoparticle Surfaces
Anuj Chhabra, Sandip Mandal, Yugang Zhang +3
The morphology of DNA is strongly influenced by its surrounding environment, including factors such as pH, salt type and valency, and the presence of polymers. Inorganic salts are…
Phase separation kinetics of 2-TIPS at low density: Cluster growth by ballistic agglomeration
Nayana Venkatareddy, Partha Sarathi Mondal, Shradha Mishra +1
We study the kinetics of two-temperature induced phase separation (2-TIPS) in dilute binary mixtures of active ("hot") and passive ("cold") particles using molecular dynamics simul…
Phase behaviour and defect structure of soft rods on a sphere
Jaydeep Mandal, Hartmut Löwen, Prabal K. Maiti
Using particle-resolved molecular-dynamics simulations, we compute the phase diagram for soft repulsive spherocylinders confined on the surface of a sphere. While crystal (K), smec…
Diffusion-entropy scaling across dimensions
Nayana Venkatareddy, Mohd Moid, Prabal K. Maiti +1
A quantitative relationship between the diffusion coefficient of a tagged particle in a liquid and the entropy of that liquid has long been sought, as it would allow entrop…
