Decay of Langmuir wave in dense plasmas and warm dense matter
S. Son, S. Ku, Sung Joon Moon
The decays of the Langmuir waves in dense plasmas are computed using the dielectric function theory widely used in the solid state physics. Four cases are considered: a classical p…
Theory of plasmon decay in dense plasmas and warm dense matter
S. Son, S. Ku, Sung Joon Moon
The decay of the Langmuir waves in dense plasmas is not accurately predicted by the prevalent Landau damping theory. A dielectric function theory is introduced, predicting much hig…
Backward Raman compression of x-rays in metals and warm dense matters
S. Son, S. Ku, Sung Joon Moon
Experimentally observed decay rate of the long wavelength Langmuir wave in metals and dense plasmas is orders of magnitude larger than the prediction of the prevalent Landau dampin…
Suppression of Landau damping via electron band gap
S. Son, S. Ku
The pondermotive potential in the X-ray Raman compression can generate an electron band gap which suppresses the Landau damping. The regime is identified where a Langmuir wave can…
Plasmon band gap generated by intense ion acoustic waves
S. Son, S. Ku
In the presence of an intense ion acoustic wave, the energy-momentum dispersion relation of plasmons is strongly modified to exhibit a band gap structure. The intensity of an ion a…
Photonic band gap and x-ray optics in warm dense matter
S. Ku, S. Son, Sung Joon Moon
Photonic band gaps for the soft x-rays, formed in the periodic structures of solids or dense plasmas, are theoretically investigated. Optical manipulation mechanisms for the soft x…
