Researchers constructed a Fibonacci state of bosons using non-Abelian dualities, and obtained the Fibonacci state by interlayer clustering of composite vortices along with flux attachment.
The Fibonacci topological order is the simplest platform for a universal topological quantum computer. While the nu = 12/5 fractional quantum Hall (QH) state has been proposed to support a Fibonacci sector, a dynamical picture of how a pure Fibonacci state may emerge in a QH system has been lacking. We use non-Abelian dualities to construct a Fibonacci state of bosons at filling nu = 2 starting from a trilayer of integer QH states. Our parent theory consists of bosonic composite vortices coupled to fluctuating U(2) gauge fields, which is dual to the theory of Laughlin quasiparticles. The Fibonacci state is obtained by interlayer clustering of the composite vortices, along with flux attachment. We use this framework to motivate a wave function for the Fibonacci state.
