The presence of acoustic plasmons in p-type (hole-doped) cuprate superconductors has now been confirmed by Dr. Ke-Jin Zhou and his team using high-resolution RIXS (Resonant Inelastic X-ray Scattering), at Diamond Light Source's I21 beamline. This discovery described in their recently published paper in Physical Review Letters opens up new opportunities to study and understand these collective charge excitations and their role in superconductivity. This may make it possible to design very-high-temperature superconductors, which lend themselves to practical applications such as highly-efficient energy transmission.
