Percolation of Hard Disks
Random arrangements of points in the plane, interacting only through a simple hardcore exclusion, are considered. An intensity parameter controls the average density of arrangements, in analogy with the Poisson point process. It is proved that, at high intensity, an infinite connected cluster of excluded volume appears almost surely.
متن کاملSpreading in narrow channels.
We study a lattice model for the spreading of fluid films, which are a few molecular layers thick, in narrow channels with inert lateral walls. We focus on systems connected to two particle reservoirs at different chemical potentials, considering an attractive substrate potential at the bottom, confining sidewalls, and hard-core repulsive fluid-fluid interactions. Using kinetic Monte Carlo simu...
متن کاملDefending Against Rogue Hard Disks
Recent revelations as to the ability of APTs to embed code in hard disk firmware, as well as the existence of prior public literature describing similar work, raise concerns as to the future potential proliferation and weaponization of this technique. We describe previous work in this domain, including both recent revelations and prior research, and then discuss our strategy for mitigating the ...
متن کاملArching in tapped deposits of hard disks.
We simulate the tapping of a bed of hard disks in a rectangular box by using a pseudodynamic algorithm. In these simulations, arches are unambiguously defined and we can analyze their properties as a function of the tapping amplitude. We find that an order-disorder transition occurs within a narrow range of tapping amplitudes as has been seen by others. Arches are always present in the system a...
متن کاملVoronoi neighbor statistics of hard-disks and hard-spheres.
The neighbor distribution in hard-sphere and hard-disk fluids is analyzed using Voronoi tessellation. The statistical measures analyzed are the nth neighbor coordination number (Cn), the nth neighbor distance distribution [fn(r)], and the distribution of the number of Voronoi faces (Pn). These statistics are sensitive indicators of microstructure, and they distinguish thermodynamic and annealed...
