【报告摘要】

In nuclear theory, the random-phase approximation (RPA), with or without pairing, has proven to be a valuable tool in the description of collective vibrations, especially giant resonances. In its self-consistent version, where the same energy density functional is used to obtain the nuclear ground state in, e.g., the Hartree-Fock approximation, and to calculate the particle-hole residual interaction, it represents linear-response theory on the mean-field level and it facilitates connections between the properties of nuclear collective motion and the equation of state of nuclear matter. Its limitations, most prominently in the description of damping mechanisms, has motivated the development and application of beyond-mean-field approaches, including second-order RPA (SRPA) and phonon-coupling approaches, which have had notable successes in analyzing and interpreting experimental data.
In this talk, I would like to discuss the first self-consistent SRPA applications, which first appeared roughly fifteen years ago, the RPA and SRPA's newly examined formal properties, and relationships of SRPA with other beyond-mean-field approaches.
