Dynamics of density fluctuations in atomic nuclei

Abstract

We study the spatiotemporal patterns of density fluctuations in ${}^{16,24}$O and ${}^{48}$Ca using nuclear interactions from chiral effective field theory and the time-dependent coupled-cluster method. We find that two-particle-two-hole excitations generate small-amplitude fluctuations that are fast, short-ranged and of stochastic character.
