DESCRIPTION:Quasicrystalline patterns posses long-range order but lack peri
 odicity. This places them in the spectrum of materials between clean\, ord
 ered crystals and disordered\, amorphous solids. They share properties of 
 both disordered structures and ordered materials\, resulting in a rich var
 iety of physical phenomena.&nbsp\;\nThis presentation discusses a novel gr
 ound state phase exhibited by our eightfold symmetric optical quasicrystal
 : the Bose glass. This is a localised phase resulting from the interplay o
 f disorder\, in the form of aperiodicity\, and interactions.\nIn this rega
 rd\, I will detail two experiments. The first experiment measures the grou
 nd state phase dia-gram of the quasicrystal as a function of both the latt
 ice depth and interaction strength. The 2D optical quasicrystal is found t
 o support both a superfluid (extended) phase and a Bose glass (localised) 
 phase.&nbsp\;\nThe second experiment explores the quench dynamics of this 
 phase transition. Rapidly crossing the BG/SF phase boundary induces transi
 ent out-of-equilibrium dynamics that depend on properties of the underlyin
 g Hamiltonian.\nThis establishes quantum quenches as a means to uncover th
 e relaxation dynamics in the long and short term following a rapid change 
 in parameter.
