Auxetic behaviour in crystals of hard polyhedra
Rinske M. Alkemade, Silvana A. Caipa Cure, AlptuÄ Ulugöl +8
Auxetic materials - systems that, when subjected to a compression in one direction, also compress in one or more perpendicular directions - have intrigued researchers for decades d…
Comment on "The elusive fluid-and-crystal coexistence state in simulations of monodisperse, hard-sphere colloids"
Frank Smallenburg
In a recent article [J. G. Wang, U. Dhumal, M. E. Zakhari, and R. N. Zia, AIChE Journal 72, e70275 (2026).], the authors discuss the absence of simulations of monodisperse hard sph…
Determining fluid-crystal phase boundaries for a binary hard-sphere mixture using direct-coexistence simulations
Rinske M. Alkemade, Alessandro Salo, Laura Filion +1
Determining fluid-crystal phase boundaries via direct-coexistence methods can be challenging due to the fact that the simulation box can introduce crystal strain. Recently, a direc…
Conservation laws and slow dynamics determine the universality class of interfaces in active matter
Raphaël Maire, Andrea Plati, Frank Smallenburg +1
While equilibrium interfaces display universal large-scale statistics, interfaces in phase-separated active and driven systems are predicted to belong to distinct non-equilibrium u…
Self-assembly of quasicrystals under cyclic shear
Raphaël Maire, Andrea Plati, Frank Smallenburg +1
We investigate the self-assembly of two-dimensional dodecagonal quasicrystals driven by cyclic shear, effectively replacing thermal fluctuations with plastic rearrangements. Using…
Vacancy defects in square-triangle tilings and their implications for quasicrystals formed by square-shoulder particles
AlptuÄ 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…
