Key Points

The study aims to explore the emergence of the golden ratio from the E8 root system in the context of icosahedral quasicrystals.
Analyzed E8 root system vertices in 8D and their projection to 3D quasicrystals.
Derived mathematical expressions for the golden ratio and its role in quasicrystal plane spacings.
Connected the geometric properties of icosahedral symmetry to Fibonacci chain spacing.
Identified golden ratio φ as approximately 1.618 in the plane spacing of icosahedral quasicrystals.
Demonstrated that E8 lattice mapping reveals vertex coordinates that include φ.
Established that quasicrystals exhibit 5-fold rotational symmetry, which is not allowed in periodic crystals.
