Article Summaries:
- MIT researchers have introduced a theory‑driven framework that turns an overlooked neutron‑scattering interference effect into a direct probe of electron‑phonon coupling-a key property governing electrical, thermal, optical, and superconducting behavior. By deliberately designing experiments to exploit the interference between nuclear and magnetic interactions, the team shows the resulting pattern is proportional to the coupling strength, enabling measurements that were previously “invisible” with conventional techniques. The approach, detailed in Materials Today Physics, could accelerate the discovery of advanced semiconductors and materials for quantum computing, and illustrates how theory can guide the design of new spectroscopy methods.
