Temperature-dependent excitonic superfluid plasma frequency evolution in an excitonic insulator, Ta2NiSe5
Abstract An interesting van der Waals material, Ta2NiSe5 has been known one of strong excitonic insulator candidates since it has very small or zero bandgap and can have a strong exciton binding energy because of its quasi-one-dimensional crystal structure. Here we investigate a single crystal Ta2Ni...
