"introducing small amount of indium into layered tantalum/ sulfur compound changes crystal structure's symmetry, leading to uniquely protected pattern where electrons with spin up/ down follow different momentum pathways (directions), until both paths merge at Kramers nodal line... precisely adjusts material’s properties, which could enable the development of the material as a topological superconductor, which may enhance power systems and computing technologies"
