How subsystem resetting can reshape phase behavior in many-body systems.

Caption

Panels (a) and (b) compare, respectively, the phase diagram of the bare model and the model with subsystem resetting at a given parameter value K=-5.0 of the bare model, showing that resetting only a fraction f of the system at a given K can reproduce in the (f,T)-plane the full phase diagram of the bare model in the (K,T)-plane.  Panel (c) shows how the steady-state order parameter of the non-reset subsystem (rstnr ) varies with temperature for different reset frequencies, revealing how resetting enables going between different types of phase transitions.
