Coexistence of long- and quasi-long range spatial order in 1D quantum quasicrystals
A. Mendoza-Coto, M. Grossklags, J. Stefaniak +2
Quasicrystals exhibit long-range positional order without periodicity, arising from multiple incommensurate wave vectors. In self-assembled quasicrystals, the spontaneous breaking…
