WebMar 14, 2024 · 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 coupling, … WebMay 22, 2024 · strongly correlated effects. After the core electron is excited, the core hole site is nearly a doubly-occupied in this Mott in-sulating phase. Since the filling factor is exactly at half orig-inally, the excess electron forms a doublon even if the elec-tron escapes from the core hole site. This doublon outside the core hole site makes the ...
Webstate with a high critical temperature. It is not clear yet whether these superconduc-tors are indeed part of the family of correlated-electron systems, but evidence is accumulating that the superconductiv-ity is unconventional. On the theory side, it is difficult to carry out reliable calculations in the context of correlated electrons ... WebUnder the strong electron correlation generating the Mott–Hubbard gap between the upper Hubbard band (UHB) and the lower Hubbard band (LHB) of the Cu 3 d x 2 − y 2 orbital, calculations based on the local density approximation (LDA) combined with the dynamical mean-field theory (DMFT) revealed the possibility of the closing of the so-called ...
