Warm dense matter is an important stage of material development in the process of inertial confinement fusion and the evolution of the universe. As the density increases, quantum effects gradually manifest, and the collective excitations in warm dense region show behavior different from the classical cases. Density-functional kinetic theory (DFKT) is a statistical model based on the time-dependent-density-functional theory and Wigner distribution function (phase-space quantum theory), which can effectively compensate for the neglect of quantum effects by classical plasma theory. Based on the DFKT, we found that properties such as Fermi-Dirac distribution, exchange-correlation effects, and quantum diffraction effects in the warm-dense characteristic parameters can inhibit the two-stream instabilities. DFKT is expected to provide a first-principle theoretical platform for the study of the transport properties of the warm dense systems from the perspective of plasmas.
