Strongly correlated materials are a wide class of compounds that include insulators and electronic materials, and show unusual (often technologically useful) electronic and magnetic properties, such as metal-insulator transitions, heavy fermion behavior, half-metallicity, and spin-charge separation. The essential feature that defines these materials is that the behavior of their electrons or spinons cannot be described effectively in terms of non-interacting entities. Theoretical model… WebNov 11, 2024 · The electron and hole sides show almost identical correlated insulating states with similar energy scales, suggesting that the same correlation effect is in play.

This may indicate that, near the regions showing correlated insulating states, a form of ferromagnetism is emerging — not superconductivity. But additional experiments would need to verify this. diseases of silkworm slideshare ppt
