Coherent order parameter oscillations in the ground state of the excitonic insulator Ta(2)NiSe(5)

The excitonic insulator is an intriguing electronic phase of condensed excitons. A prominent candidate is the small bandgap semiconductor Ta(2)NiSe(5), in which excitons are believed to undergo a Bose-Einstein condensation–like transition. However, direct experimental evidence for the existence of a...
