Coercivity landscape in driven stochastic φ⁴ and Curie-Weiss models shows a plateau at v_P with H_P; scalings are H_c ~ v_H below, H_c ~ v_H^{1/2} in fast driving, and H_c - H_P ~ (v_H - v_P)^{2/3} post-plateau, with universal slow-driving behavior except in fast regime.

In the stochastic φ⁴ model, coercivity exhibits v_H scaling, a plateau at the first-order transition field H*, then v_H^{1/2} scaling, with finite-size scalings v_P ~ σ² and (H* - H_P) ~ σ^{4/3} from renormalization-group theory.
In the Z3 chiral clock model, DQPTs emerge only for special angles in the chiral phase, with an analytical expression derived for the zeros of the dynamical partition function.

Finite-time and Finite-size scalings of coercivity in dynamic hysteresis
Coercivity landscape in driven stochastic φ⁴ and Curie-Weiss models shows a plateau at v_P with H_P; scalings are H_c ~ v_H below, H_c ~ v_H^{1/2} in fast driving, and H_c - H_P ~ (v_H - v_P)^{2/3} post-plateau, with universal slow-driving behavior except in fast regime.
