Kondo lattice model

The Kondo lattice model describes how conduction electrons interact with a regular array of magnetic atoms embedded in a material. These magnetic atoms each have a tiny magnetic moment, and as conduction electrons move through the material, they tend to align their spins opposite to these moments, leading to complex collective behaviors. This interaction can result in unusual electrical properties like heavy electron masses and low-temperature resistance drops. The model helps understand phenomena in certain metals and compounds, especially those that display unconventional magnetism and superconductivity arising from the interplay between electron movement and magnetic order.
