Substrate-Mediated Evaporation and Stochastic Evolution of Supported Au Nanoparticles
Dmitri N. Zakharov, Xiaohui Qu, Hong Wang +6
We use in situ transmission electron microscopy with automated tracking to study supported gold nanoparticles (NPs) during high-temperature vacuum annealing. \rev{The average mass…
Chaos over Order: Mapping 3D Rotation of Triaxial Asteroids and Minor Planets
Valeri V. Makarov, Alexey Goldin, Alexei V. Tkachenko +2
Celestial bodies approximated with rigid triaxial ellipsoids in a two-body system can rotate chaotically due to the time-varying gravitational torque from the central mass. At smal…
Controlling morphology in hybrid isotropic/patchy particle assemblies
Srinivas Mushnoori, Jack A. Logan, Alexei V. Tkachenko +1
Brownian Dynamics is used to study self-assembly in a hybrid system of istotropic particles (IPs), combined with anisotropic building blocks that represent special "designer partic…
Symmetry-specific orientational order parameters for complex structures
Jack A. Logan, Srinivas Mushnoori, Meenakshi Dutt +1
A comprehensive framework of characterizing complex self-assembled structures with a set of orientational order parameters is presented. It is especially relevant in the context of…
Geometric and Topological Entropies of Sphere Packing
Jack A. Logan, Alexei V. Tkachenko
We present a statistical mechanical description of randomly packed spherical particles, where the average coordination number is treated as a macroscopic thermodynamic variable. Th…
Stochastic social behavior coupled to COVID-19 dynamics leads to waves, plateaus and an endemic state
Alexei V. Tkachenko, Sergei Maslov, Tong Wang +3
It is well recognized that population heterogeneity plays an important role in the spread of epidemics. While individual variations in social activity are often assumed to be persi…
