Active-Passive Unified Room-Temperature Superconductivity: From Theoretical Definition to Engineering Realization of Lanthanum Hydride and Hydrogen-Rich Lanthanide Materials

This paper presents an active-passive unified room-temperature superconductivity scheme, extending the realization of superconductivity from the design of static structures of specialized materials to the active excitation of ordinary materials. The passive pathway constructs an S=0 junction pair network through boron-beryllium co-doped diamond, achieving static room-temperature superconductivity with Tc = 302.7 K. The active pathway triggers neutron pair head-on collisions through pre-embedded excitable neutron pairs within the material, releasing directional electrons under mild external energy excitation, thereby generating zero-resistance currents in lanthanum hydride and hydrogen-rich lanthanide materials. This paper details an extremely simple preparation method for hydrogen-rich lanthanide materials — filling hydrogen into lanthanum lattice interstices under ambient pressure and moderate temperature conditions, utilizing the dense arrangement of hydrogen atoms to naturally form a large number of symmetric junction stagnation neutron pairs. The preparation itself establishes the energy source and pathways required for superconductivity. The two mechanisms synergistically enhance each other in a unified system, pushing Tc to 315.1 K (41.95°C), covering summer daily maximum temperatures, and achieving year-round, season-unrestricted room-temperature superconductivity for practical applications.
