In atomic physics, a Fibonacci chain is a chain of atoms that contains two atom species, A and B. The B atoms are separated by either one or two A atoms in an irregular sequence. Thanks to the irregularity of the pattern, these Fibonacci chains are quasicrystals in which rich collective behaviors can emerge. Creating circuit analogs of atomic systems allows researchers to fashion Fibonacci chains from capacitors, inductors, and resistors. Now Selma Franca of the Institut Néel in France and her collaborators have built such an electronic Fibonacci chain from off-the shelf electronic components and have devised a simple way to characterize the chain’s complex physics [1].
