Inelastic X-Ray Scattering Study of Exciton Properties in an Organic Molecular crystal (2006)

Yang, K., Chen, L. P., Cai, Y. Q., Hiraoka, N., Li, S., Zhao, J. F., ...

Excitons in a complex organic molecular crystal were studied by inelastic x-ray scattering (IXS) for the first time. The dynamic dielectric response function is measured over a large momentum...

Low-Energy Charge-Density Excitations in MgB$_{2}$: Striking Interplay between Single-Particle and Collective Behavior for Large Momenta (2006)

Cai, Y. Q., Chow, P. C., Restrepo, O. D., Takano, Y., Togano, K., Kito, H., ...

A sharp feature in the charge-density excitation spectra of single-crystal MgB$_{2}$, displaying a remarkable cosine-like, periodic energy dispersion with momentum transfer ($q$) along the...
