Quasicrystals are long-range ordered and yet nonperiodic. This interplay results in a wealth of intriguing physical phenomena, such as the inheritance of topological properties from higher dimensions, and the presence of nontrivial structure on all scales. Here, we report on the first experimental demonstration of an eightfold rotationally symmetric optical lattice, realizing a two-dimensional quasicrystalline potential for ultracold atoms. Using matter-wave diffraction we observe the self…

This work demonstrates the importance of quantum fluctuations in the formation of sub-wavelength phase structure of a Bose-Einstein condensate with two-dimensional optical lattice by considering different lattice configurations and provides a powerful tool for exploring the fineructure of a lattice cell as well as topological defects in matter wave.
