Electronic-Structure Control of Nuclear Excitation by Electron Capture in Finite-Density $^{229}$Th
Nuclear excitation by electron capture (NEEC) provides a unique pathway for coupling electronic and nuclear dynamics, but its description in dense matter commonly relies on electronic structures of isolated ions. Here we show how dense environments reshape the available NEEC capture channels. Using a finite-temperature...
