The phonon density of states (PDOS) has been evaluated on the basis of many-body quantum dynamical Green’s function theory via an almost complete Hamiltonian, which includes the effects of electrons, phonons, anharmonicities, defects, and electron-phonon interactions. The numerical and graphical assessment of the obtained results, executed for La2-xSrxCuO4 cuprate high-temperature superconductor (HTS), predicts several new features of high-temperature superconductors and is consistent with the experimental results. |
