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…
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…
Dynamical and structural properties of an absorbing phase transition: a case study from granular systems
Raphael Maire, Andrea Plati, Frank Smallenburg +1
We investigate the dynamical and structural properties of absorbing phase transitions (APTs) within granular systems. Specifically, we examine a model for vibrofluidized systems of…
Non-equilibrium coexistence between a fluid and a hotter or colder crystal of granular hard disks
R. Maire, A. Plati, F. Smallenburg +1
Non-equilibrium phase coexistence is commonly observed in both biological and artificial systems, yet understanding it remains a significant challenge. Unlike equilibrium systems,…
Self-assembly and non-equilibrium phase coexistence in a binary granular mixture
A. Plati, R. Maire, F. Boulogne +3
We report the experimental observation of a square crystalline phase in a vibrated binary mixture of spherical grains. This structure spontaneously forms from a disordered state, c…
