Title: Algebraic invariants of non-equilibrium dynamics based on lagged second-order statistics

Abstract: 

In phase-separation transitions, particles aggregate into macroscopic high-density clusters that often span the system and generate percolating structures. In two dimensions, percolation and phase separation occur simultaneously, yet their critical scaling properties remain distinct while deeply related. In this talk, Prof. PK Mohanty will examine this connection in active matter systems and show how percolation concepts provide a powerful route to understanding motility-induced phase separation (MIPS). 

Using run-and-tumble particle dynamics as a representative example, Prof. PK Mohanty will present evidence that MIPS transitions can be placed within an Ising-type super-universality class, offering a unified perspective on critical phenomena in nonequilibrium active systems.
