Thermal Excitation Signals in the Inhomogeneous Warm Dense Electron Gas
Thermal Excitation Signals in the Inhomogeneous Warm Dense Electron Gas
Moldabekov, Z.; Dornheim, T.; Cangi, A.
We investigate the emergence of electronic excitations from the inhomogeneous electronic structure at warm dense matter parameters based on first-principles calculations. The emerging modes are controlled by the imposed perturbation amplitude. They include satellite signals around the standard plasmon feature, transformation of plasmons to optical modes, and double-plasmon modes. These modes exhibit a pronounced dependence on the temperature. This makes them potentially invaluable for the diagnostics of plasma parameters in the warm dense matter regime. We demonstrate that these modes can be probed with present experimental techniques.
