The J1-J2 model is a type of theoretical model often used in condensed matter physics, particularly in the study of magnetism and spin systems. It describes interactions between neighboring spins on a lattice. The notation "J1" and "J2" refers to the strengths of the exchange interactions between these spins. 1. **J1 Interaction**: This typically represents the nearest-neighbor interaction.
