Destabilizing excitonic insulator phase by pressure tuning of exciton-phonon coupling
Ta_{2}NiSe_{5} is an excitonic insulator (EI) exhibiting bound electron-hole pairs condensed at room temperature, which transforms to a small-gap semiconducting state above T=325 K simultaneously undergoing a phonon-related structural transition. Despite the clear experimental evidence for strong ex...
