Compatible Condensation and Generalized Gauging: Marked Transport and Wall Interchange
Abstract
We formulate condensation compatible with a specified separable generalized gauging operation in a unitary (2 + 1)-dimensional defect realization. Compatibility is a coherent reversible crossing of the full condensate algebra, retaining charged channels and the marked condensation interface. The resulting composite network determines the transported condensate, the induced operation, and a commuting square of specified walls. For connected gauging data, compatibility admits a central matching description that retains the transported condensate and its algebra identification on the specified wall. The specified unit may absorb a nontrivial parent anyon algebra; strong connectedness appears only as the transparent-unit specialization. We distinguish original vacuum insertions, vacuum branches after unit absorption, and the full vacuum algebra of the final phase, and we prove a complete Higgs criterion that incorporates the parent algebra absorbed by the specified unit. In the toric-code example of a non-invertible subgroup gauging we classify the compatible condensations for the fixed operation, exhibit two inequivalent crossings of the same parent condensate that lead to different final phases, and analyse a pure condensation operation in which the specified unit absorbs the parent electric condensate and produces additional final vacuum operators. The transparent-unit case recovers reverse-condensation transport and the vacuum-overlap formula, and the three complete Higgs conditions appear as a corollary of the general criterion.
