Another challenge to studying time crystals is the fact the periodic driving of a many-body system causes the system to heat up, eventually reaching a temperature that would destroy both spatial and temporal crystalline order. This fate can be evaded ... WebPrimitive unit cells are defined as unit cells with the smallest volume for a given crystal. (A crystal is a lattice and a basis at every lattice point.) To have the smallest cell volume, a primitive unit cell must contain (1) only one lattice point and (2) the minimum amount of basis constituents (e.g., the minimum number of atoms in a basis).
