Mean-field phases of an ultracold gas in a quasicrystalline potential
Dean Johnstone, Patrik Öhberg, Callum W. Duncan
The recent experimental advancement to realise ultracold gases scattering off an eight-fold optical potential [Phys. Rev. Lett. 122, 110404 (2019)] heralds the beginning of a new t…
