Nonmagnetic molecular Jahn-Teller Mott insulators
Nonmagnetic molecular Jahn-Teller Mott insulators
Narrow-band conductors may turn insulating and magnetic as a consequence of strong electron-electron correlation. In molecular conductors, the concomitance of a strong Jahn-Teller coupling may give rise to the alternative possibility of a non-magnetic insulator, with or without a static cooperative Jahn-Teller distortion. In the latter case the insulator has …
