Vacancy defects in square-triangle tilings and their implications for quasicrystals formed by square-shoulder particles
Alptuğ Ulugöl, Giovanni Del Monte, Eline K. Kempkes +2
Almost all observed square-triangle quasicrystals in soft-matter systems contain a large number of point-like defects, yet the role these defects play in stabilizing the quasicryst…

Solid-angle based nearest-neighbor algorithm adapted for systems with low coordination number
Alptuğ Ulugöl, Frank Smallenburg, Laura Filion
Nearest-neighbor identification is central to the analysis of local structure in condensed matter systems. The solid-angle-based nearest-neighbor (SANN) algorithm is widely used of…

Defects Enhance Stability in 12-fold Symmetric Soft-Matter Quasicrystals
Alptuğ Ulugöl, Robert J. Hardeman, Frank Smallenburg +1
Quasicrystals are materials that exhibit long-range order without translational periodicity. In soft matter, the most commonly observed quasicrystal has 12-fold symmetry and consis…
