    Tuning orbital-selective phase transitions in a two-dimensional Hund’s correlated system

    Hund’s rule coupling (J) has attracted much attention recently for its role in the description of the novel quantum phases of multi-orbital materials. Depending on the orbital occupancy, J can lead to various int...

    Colossal flexoresistance in dielectrics

    Dielectrics have long been considered as unsuitable for pure electrical switches; under weak electric fields, they show extremely low conductivity, whereas under strong fields, they suffer from irreversible da...
