Topological Superconducting Engineering: From Logical Universe Information Dynamics to High-Temperature Superconductor Design ——A Theoretical and Engineering Guide to Finding Zero-Dissipation Paths

The mechanism of high-temperature superconductivity and the discovery of new materials have long been plagued by theoretical fragmentation and the lack of unified screening criteria. Based on the Logical Universe (LU_v3.1) information-ontological framework, this paper redefines the superconducting state as the zero-dissipation closed-loop circulation path locking of a globally coherent single information soliton——i.e., when the topological closure degree of the right-handed light field ρ_R reaches a critical threshold, the system spontaneously locks into a global circulation path without breakpoints. From this, we derive the universal superconductivity criterion: {χ δleft(T)} where χ is the intrinsic chiral purity of the system (the condensed-matter mapping of the topological closure degree Θknot), and δleft(T) is the thermal topological impurity concentration (the thermally excited component of the logical deficiency δ). This criterion does not depend on any specific pairing mechanism and uniformly applies to conventional BCS superconductors, cuprates, iron-based, heavy-fermion, and chiral superconducting systems. This paper further demonstrates that: Zero resistance = closed topological path without breakpoints (information dissipation channel closed); Meissner effect = zero-dissipation global topological compensation of the global soliton against external magnetic fields (macroscopic manifestation of the deficiency-compensation duality); Flux quantization = integrality constraint of the winding number of the closed topological soliton. These three are three facets of the same topological structure (the globally coherent single information soliton); their coexistence is not an experimental coincidence but a necessary consequence of the Logical Universe axiom system. We propose four design principles for high-T_c superconducting materials, a three-tier material screening priority, and four falsifiable experimental predictions. This framework does not replace BCS theory but provides a deeper topological criterion: superconducting performance is dominated by the relative magnitude of the system's chiral purity and thermal topological impurities; the essence of high-T_c superconductivity engineering is χ-engineering.
