Role of electron-phonon coupling in excitonic insulator candidate Ta_{2}NiSe_{5}

Role of electron-phonon coupling in excitonic insulator candidate Ta_{2}NiSe_{5}

Electron-hole bound pairs, or excitons, are common excitations in semiconductors. They can spontaneously form and condense into a new insulating ground state—the so-called excitonic insulator—when the energy of electron-hole Coulomb attraction exceeds the band gap. In the presence of electron-phonon...
