Title: Controlling attainment of spontaneous ordering in many-body interacting systems

Speaker: Prof. Shamik Gupta, TIFR

Abstract: Consider a thermodynamic system that shows a phase transition between an ordered and a disordered phase. The question we ask is: in the parameter regime in which the system exhibits a disordered phase, can we induce order by manoeuvring the system through forcefully establishing order in a small subset of the system constituents ? Within the ambit of the Kuramoto model, a paradigmatic nonlinear dynamical many-body system, we discuss analytical results on how the aforementioned dynamical scheme leads to a rich dynamics, and, most remarkably, establishing of macroscopic order even in parameter regimes in which the bare dynamics does not support any such ordering.
