Description
In this work, we introduce additional dimer degrees of freedom into classical spin models and investigate their thermodynamic behavior using Monte Carlo simulations. The dimers represent locally correlated spin pairs and are dynamically created, annihilated, and rearranged together with classical spin configurations. This semiclassical approach allows us to study the interplay between magnetic correlations and dimer formation beyond conventional classical spin Monte Carlo simulations. We apply this framework to the square and square-kagome lattices and examine how geometrical frustration affects the formation and spatial organization of dimers. Our results provide a simple classical framework for exploring dimer-dominated disordered states and their possible connection to spin-liquid-like behavior in frustrated magnets.
