The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

Abstract Characterization of the morphology, identification of patterns and quantification of
order encountered in colloidal assemblies is essential for several reasons. First of all, it is …

We study the melting of quasi-two-dimensional colloidal hard spheres by considering a tilted
monolayer of particles in sedimentation-diffusion equilibrium. In particular, we measure the …

It is generally believed that collisions of particles reduce the self-diffusion coefficient. Here
we show that in odd-diffusive systems, which are characterized by diffusion tensors with …

Relating thermodynamic and kinetic properties is a conceptual challenge with many
practical benefits. Here, based on first principles, we derive a rigorous inequality relating the …

Driven by physical questions pertaining to quantifying particle dynamics, microscopy can
now resolve complex systems at the single-particle level, from cellular organisms to …

Odd-diffusive systems are characterized by transverse responses and exhibit
unconventional behaviors in interacting systems. To address the dynamical interparticle …

Among the key insights into the glass transition has been the identification of a
nonequilibrium phase transition in trajectory space which reveals phase coexistence …

Hard disks are one of the simplest interacting many-body model system in two dimensions
(2D). Here, we present a comprehensive set of measurements of the static structure factors …

Nearly monodisperse nanoparticle (NP) spheres attached to a nonvolatile ionic liquid
surface were tracked by in situ scanning electron microscopy to obtain the tracer diffusion …
