Are lattices only found in solids?

Lattices are primarily associated with solids, particularly in the context of crystalline structures where atoms are arranged in a regular, repeating pattern. However, lattice-like arrangements can also be observed in certain liquids and gases under specific conditions, such as in the formation of colloidal crystals or during phase transitions. In these cases, the arrangement is not as rigid or permanent as in solids. Overall, while lattices are most commonly linked to solids, they can appear in other states of matter under certain circumstances.
