| contents | Unifying equilibrium criticality and dynamical quantum phase transitions (DQPTs) under complex driving fields remains a profound challenge. Here, we decode this connection in the 2D strongly interacting Wen-plaquette model. By mapping its anyonic excitations to 1D effective dissipative channels, we reveal that microscopic single-particle fidelity zeros exactly reconstruct the macroscopic equilibrium topological phase boundaries. Beyond equilibrium, we demonstrate that during non-unitary quench dynamics, these very same static singularities enforce an absolute momentum-space exclusion against dynamical Fisher zeros. Furthermore, a newly identified dissipation-phase racing mechanism prematurely depletes the decaying mode, fundamentally annihilating DQPTs and generating topologically trivial steady states. Our results establish exact microscopic static singularities as the universal decoder for macroscopic non-unitary topological dynamics. |
