Description

Accurate modeling of nuclear dynamics is essential to understand how chemical elements are formed in stars and other extreme astrophysical environments. Such dynamical processes are naturally described by the time-dependent Schrödinger equation. In this talk, I will introduce a time-dependent coupled-cluster approach to solve it. As a first application, I will focus on how to compute nuclear response functions from the time evolution of the many-body wave function. I will show that this new method is in excellent agreement with static results for electric dipole responses in light and medium-mass nuclei. I will also discuss how the picture of giant and pygmy dipole resonances as collective oscillations of protons against neutrons emerge from evolving proton and neutron densities in time, and present results in the strong-field regime, where the system exhibits signatures of chaotic behavior.
