abstract:
Geometrical frustration arises when a local order cannot propagate
throughout the space because of geometrical constraints. This phenomenon
plays a major role in many systems leading to disordered ground-state
configurations. Here, we report a theoretical and experimental study on
the behavior of buckling-induced geometrically frustrated triangular
cellular structures. To our surprise, we find that buckling induces
complex ordered patterns which can be tuned by controlling the porosity
of the structures. Our analysis reveals that the connected geometry of
the cellular structure plays a crucial role in the generation of ordered
states in this frustrated system.
