Extended Data Fig. 8: Non-commutative state transition of the two-layer chiral metamaterial.
a, The possible states of the metamaterial. A two-bit number is used to indicate the global states, with each bit representing an entire layer. For each bit, the digit 1 indicates that the layer is deployed, and the digit 0 indicates that the layer is folded. b–e, Experimental loading curves for state transitions (b) starting from 11 with a anticlockwise rotation followed by a clockwise rotation, (c) starting from 11 with a clockwise rotation followed by a anticlockwise rotation, (d) starting from 00 with a clockwise rotation followed by a anticlockwise rotation, (e) starting from 00 with a anticlockwise rotation followed by a clockwise rotation. The peak torques that trigger the state transitions are indicated in the plots.
