【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.

She earned her Diploma in 1995, MSc in 1998, and Ph.D. in 2003 from the National Kapodistrian University of Athens, Greece. After obtaining her Ph.D., she served as a Research Associate at the Darmstadt University of Technology in Germany from 2003 to 2011 and as a Postdoctoral Researcher at CNRS/Paris-Sud University in France from 2011 to 2013. She joined the Institute for Basic Science in South Korea as a Principal Researcher/Research Fellow in 2013 and has held her current role since 2019. Her research interests focus on theoretical nuclear physics, quantum many-body physics, and rare-isotope science.

Dr. Papakonstantinou has made notable contributions to her fields. She has been invited to speak at numerous international conferences and has published over 70 papers with more than 1,200 citations.
