Fibonacci topological phase in arrays of anyonic chains

A bstract Fibonacci anyon, an exotic quasi-particle excitation, plays a pivotal role in realization of a quantum computer. Starting from a SU (2) 4 topological phase, in this paper we demonstrate a way to construct a Fibonacci topological phase which has only one non-trivial excitation described by the Fibonacci anyon. We show that arrays of anyonic chains created by excitations of the SU(2) 4 phase leads to the Fibonacci phase. We further demonstrate that our theoretical propositions can be extended to other topological phases.
