Absence of first-order transition and tricritical point in the dynamic phase diagram of a spatially extended bistable system in an oscillating field
It has been well established that spatially extended, bistable systems that are driven by an
oscillating field exhibit a nonequilibrium dynamic phase transition (DPT). The DPT occurs …
