Geometric frustration occurs in systems where the arrangement of particles or spins cannot simultaneously satisfy all interactions due to conflicting geometric constraints. This phenomenon is often observed in materials with complex lattice structures, where the local interactions lead to a highly degenerate ground state, meaning there are many possible configurations that the system can adopt. In condensed matter physics, geometric frustration is significant because it can lead to unusual properties, such as spin liquids or non-trivial magnetic states. Examples of systems exhibiting geometric frustration include certain types of magnetic materials and triangular lattices, where the inability to minimize energy results in rich and complex behaviors.
