Crystallographic refinement of collective excitations using standing wave inelastic x-ray scattering
Yu Gan, Anshul Kogar, Peter Abbamonte
We propose a method for realizing true, real-space imaging of charge dynamics in a periodic system, with angstrom spatial resolution and attosecond time resolution. In this method,…

First-principles method of propagation of tightly bound excitons: exciton band structure of LiF and verification with inelastic x-ray scattering
Chi-Cheng Lee, Xiaoqian M. Chen, Yu Gan +4
We propose a simple first-principles method to describe propagation of tightly bound excitons. By viewing the exciton as a composite object (an effective Frenkel exciton in Wannier…
