资源简介:

Dataset of double well potentials sampled from energy landscape exploration of a ternary Lennard-Jones model supporting: "Microscopic observation of two-level systems in a metallic glass model" Thermalised configurations of the ternary Lennard-Jones model are given in the archive (configs.zip) of 1200 atoms at \(T_f\) 0.488, 0.509, 0.558 and 0.617 in the lammps (https://www.lammps.org/) data file format (https://docs.lammps.org/read_data.html). The two datasets each provided as (.zip) archives named dataset1.zip and dataset2.zip Datafiles (.csv) are named nebdf_{:3.3f}_{:05d}.csv where the float is \(T_f\) and the integer is \(\tilde{m}\). columns of each .csv file are: 'transitions', 'forward barriers', 'reverse barriers', 'asymmetry', 'barrier', 'euclidean distance', 'distance along string', 'n_intermediates', 'deltas', 'splittings', 'delta_zeroes', 'gammas', 'PR', 'glass', 'omegas1', 'omegas2', 'omegasts', 'Index 1', 'Index 2', 'Frequency 1>2', 'Frequency 2>1', 'e_1', 'e_2', 'dc', 'Tprep' 'glass' is the index of the glassy metabasin sampled omegas1', 'omegas2', 'omegasts' are the curvatures of the minimum energy oaths near the first minimum, second minimum and transition state 'e_1', 'e_2' are the energy per atom of the two glass minima 'dc' is the typical particle displacement corresponding to \(\sqrt{\dfrac{d^2}{PR}}\)

本数据集为支撑"金属玻璃模型中两能级系统的微观观测"研究的三元朗道-琼斯(Lennard-Jones)模型能量景观探索所采样得到的双势阱数据集。 该三元朗道-琼斯模型的热平衡构型存储于configs.zip压缩包中,包含1200个原子的构型,对应的温度因子(T_f)分别为0.488、0.509、0.558及0.617,文件格式采用LAMMPS(https://www.lammps.org/)数据文件格式(规范参考https://docs.lammps.org/read_data.html)。 本次提供两个数据集,分别以dataset1.zip与dataset2.zip两个压缩包形式存储。 数据文件为.csv格式,命名规则为`nebdf_{:3.3f}_{:05d}.csv`,其中浮点数部分对应(T_f),整数部分为( ilde{m})。 每个.csv文件的列依次为:transitions(跃迁次数)、forward barriers(正向势垒)、reverse barriers(反向势垒)、asymmetry(不对称性)、barrier(势垒)、euclidean distance(欧氏距离)、distance along string(沿路径字符串的距离)、n_intermediates(中间态数目)、deltas(Δ值)、splittings(分裂量)、delta_zeroes(Δ零点)、gammas(γ值)、PR(PR参数)、glass(玻璃态亚阱索引)、omegas1、omegas2、omegasts、Index 1(索引1)、Index 2(索引2)、Frequency 1>2(1→2跃迁频率)、Frequency 2>1(2→1跃迁频率)、e_1、e_2、dc、Tprep。 其中: - `glass`为所采样的玻璃态亚阱的索引; - `omegas1`、`omegas2`、`omegasts`分别为第一极小点、第二极小点及过渡态附近最低能量路径的曲率; - `e_1`、`e_2`为两个玻璃态极小点的每原子能量; - `dc`为对应(sqrt{frac{d^2}{PR}})的典型粒子位移。
