Phonon occupancy
WebAug 2, 2024 · The right panel of figure 11 presents the phonon occupancy obtained by fixing the detuning at this value and increasing the gain, showing a clear reduction towards instability, i.e. . In this regime feedback is able to further cool both vibrational modes, lowering the corresponding occupancies by one order of magnitude. WebIn this phenomenon, the phonon leads to ion motion which perturbs the highest occupied valence state (HOS). This state begins to overlap with the lowest unoccupied conduction state (LUS), and the electron can switch states if energy and momentum are conserved. If it does, an electron-hole pair is generated.
