Two dimensional ideal jammed disk packing configurations and corresponding mechanical and thermal data

The ideal glass, a disordered system of particles with zero
configurational entropy, cannot be realized through thermal processes.
This dataset contains a set of ideal jammed packings of soft spheres, a
zero temperature realization of the ideal glass, produced using athermal
circle packing methods in two dimensions with pyCudaPacking software
package. It includes ideal packings and corresponding non-ideal packings
with identical radii. The number of particles in each ranges from 64 to
8192. Additionally, bulk and shear moduli at a range of densities, density
of states, spectral density and melting temperature/density corresponding
to included packings are also included. These data indicate that packings
generated using circle packing methods display thermal and mechanical
properties usually associated with the two dimensional hexagonal crystal,
in contrast with the usual behavior of ordinary glass/jammed systems in
two dimensions.

理想玻璃（ideal glass）是一类构型熵（configurational entropy）为零的粒子无序体系，无法通过热过程实现。本数据集包含一系列软球（soft spheres）理想阻塞堆积（jammed packing）样本——这类样本是理想玻璃在零温下的实现形式，通过二维非热圆堆积（athermal circle packing）方法结合pyCudaPacking软件包生成。数据集包含半径一致的理想堆积与对应非理想堆积样本，单份样本的粒子数介于64至8192之间。此外，数据集还收录了对应样本在一系列密度下的体积模量（bulk modulus）与剪切模量（shear modulus）、态密度（density of states）、谱密度（spectral density），以及与所收录堆积对应的熔化温度/熔化密度相关数据。上述数据表明，通过圆堆积方法生成的堆积体展现出通常仅在二维六角晶体中观测到的热学与力学特性，这与二维普通玻璃/阻塞体系的常规行为截然不同。
