Local composition fluctuations act as precursors for crystal nucleation in polydisperse hard spheres
Marjolein de Jager, Antoine Castagnède, Frank Smallenburg +1
We revisit the effect of polydispersity on the crystal nucleation of hard spheres. Using event-driven molecular dynamics simulations, we obtain the nucleation rate as a function of…
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…
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…
Comparing dimensionality reduction methods for local structural identification in colloidal systems
Alptuğ Ulugöl, Jessi Bückmann, Ruizhi Yang +4
Quantifying local structures in self-assembled systems is a central challenge in soft matter and materials science. When no a priori knowledge of the relevant structures is availab…
Characterizing the cage state of glassy systems and its sensitivity to frozen boundaries
Rinske M. Alkemade, Frank Smallenburg, Laura Filion
Understanding the role that structure plays in the dynamical arrest observed in glassy systems remains an open challenge. Over the last decade, machine learning (ML) strategies hav…
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…
Freezing line of polydisperse hard spheres via direct-coexistence simulations
Antoine Castagnède, Laura Filion, Frank Smallenburg
In experimental systems, colloidal particles are virtually always at least somewhat polydisperse, which can have profound effects on their ability to crystallize. Unfortunately, ac…
The Free-Energy Barrier of Precritical Nuclei in Hard Spheres is Consistent with Predictions
Lars Kürten, Antoine Castagnède, Frank Smallenburg +1
Predicting crystal nucleation is among the most significant long--standing challenges in condensed matter. In the system most studied (hard sphere colloids), the comparison between…
Machine learning short-ranged many-body interactions in colloidal systems using descriptors based on Voronoi cells
Rinske M. Alkemade, Rastko Sknepnek, Frank Smallenburg +1
Machine learning (ML) strategies are opening the door to faster computer simulations, allowing us to simulate more realistic colloidal systems. Since the interactions in colloidal…
