The structure of a state emerging from the decay process of the Higgs mode. Panels on the bottom row show the absolute value of the order parameter, and panels on the top row show the phase of the order parameter.

Through numerical simulations with time-dependent density-functional theory and the technique of the interaction quench, we verify the previous theoretical predictions on the mode's frequency. Next, we demonstrate that the mode is dynamically unstable against external perturbation and qualitatively examine the emerging state after the mode decays.
