2D topological Kondo insulator observed in a moiré superlattice
When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give rise to the so-called Kondo effect.

When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give rise to the so-called Kondo effect. A Kondo insulator is a state of matter with an energy gap opened by the Kondo effect that forbids electrical conduction at low temperatures.
