Configurational entropy of binary hard-disk glasses: nonexistence of an ideal glass transition.
We study the thermodynamics of a binary hard-disk mixture in which the ratio of disk diameters is kappa=1.4. We use a recently developed molecular dynamics algorithm to calculate the free-volume entropy of glassy configurations and obtain the configurational entropy (degeneracy) of the supercompressed liquid as a function of density. We find that the configurational entropy of the glasses near ...
متن کاملCrystallization of hard-sphere glasses.
We study by molecular dynamics the interplay between arrest and crystallization in hard spheres. For state points in the plane of volume fraction (0.54 <or= varphi <or= 0.63) and polydispersity (0 <or= s <or= 0.085), we delineate states that spontaneously crystallize from those that do not. For noncrystallizing (or precrystallization) samples we find isodiffusivity lines consistent with an idea...
متن کاملSecurity of Hard Disk Encryption
Encryption is the art of preserving confidentiality of digital information. It is considered to be one of the most ideal solutions for providing data confidentiality and safety of computer hard disk. Many disk encryption software are commercially available with a variety of features. But how much effective security is provided by those software is the ultimate question. Encryption algorithms us...
متن کاملCrystallization mechanism of hard sphere glasses.
In supercooled liquids, vitrification generally suppresses crystallization. Yet some glasses can still crystallize despite the arrest of diffusive motion. This ill-understood process may limit the stability of glasses, but its microscopic mechanism is not yet known. Here we present extensive computer simulations addressing the crystallization of monodisperse hard-sphere glasses at constant volu...
متن کاملTape Based Magnetic Recording: Technology Landscape Comparisons with Hard Disk Drive and Flash Roadmaps
This paper describes the areal density (bits per unit area) roadmap goals for tape based magnetic recording (TAPE) and uses these goals as counterpoints for the areal density roadmap strategies for Hard Disk Drive (HDD) and NAND flash. Technology comparisons described in this paper will show that presently volumetric densities (bits per unit volume) for TAPE, HDD, and NAND are similar and that ...
