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…
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…
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…
Growth Laws and Universality in 2-TIPS: Microscopic and Coarse grained approach
Nayana Venkatareddy, Partha Sarathi Mondal, Jaydeep Mandal +2
Two temperature induced phase separation(2-TIPS) is a phenomenon observed in mixtures of active and passive particles modeled by scalar activity where the temperature of the partic…
