Doping a mott insulator
WebOct 15, 2024 · A common avenue to induce IMTs in Mott insulators is doping, which inevitably leads to disorder. While disorder is well known to create electronic inhomogeneity, recent theoretical studies have indicated that it may play an unexpected and much more profound role in controlling the properties of Mott systems. Theory predicts that disorder … WebNov 15, 2024 · First, doping this Mott insulator under a certain range of magnetic fields gives rise to a dilute gas of spin polarons, which form a pseudogap metal and result in a doping-dependent magnetization plateau. Second, the application of an electric field between the two layers can invert the many-body gap of a charge-transfer Mott …
