Room-Temperature Superconductivity at 298 K in Ternary La-Sc-H System at High-pressure Conditions

The research operates within the established paradigm of condensed matter physics that seeks high-temperature superconductivity in hydrogen-rich materials under extreme pressure. This paradigm posits that hydrogen-based clathrate structures can achieve high critical temperatures (Tc). This paper extends the paradigm from binary (e.g., LaH10) to ternary systems (La-Sc-H), proposing a revolutionary breakthrough by claiming the first experimental realization of room-temperature superconductivity (RTS), the long-sought "holy grail" of the field. If validated, this would shift the paradigm from the search for RTS to the study and characterization of a confirmed RTS material.

This preprint is classified as a Model Revolution because it claims to have solved the central, century-long puzzle of achieving room-temperature superconductivity. The authors report synthesizing a La-Sc-H compound that exhibits superconductivity up to 298 K, providing evidence through zero electrical resistance and suppression of the critical temperature by a magnetic field. This is not an incremental advance within normal science but a claimed fundamental breakthrough. By demonstrating a viable material that overcomes the ambient temperature barrier, the work aims to initiate a new era of research, transforming a theoretical quest into an experimental reality.
