Deskripsi
Exotic states of solid-state matter give rise to collective excitations that can be probed by ultrafast spectroscopy. Here, a series of charge-density-wave amplitude modes are observed in a non-magnetic pnictide whose robustness against perturbations indicate an unconventional formation mechanism.
