Data supporting: Microscopic observation of two-level systems in a metallic glass model
收藏资源简介:
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 \(\sqrt{\dfrac{d^2}{PR}}\)
本数据集为基于三元伦纳德-琼斯(Lennard-Jones)模型的能量景观探索所采样得到的双势阱数据集,相关研究主题为“金属玻璃模型中两能级系统的微观观测”。 归档文件configs.zip中包含该三元伦纳德-琼斯模型的热平衡构型,体系包含1200个原子,模拟温度参数(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(详见https://docs.lammps.org/read_data.html)。 本次共提供两组数据集,分别打包为dataset1.zip与dataset2.zip两个压缩归档。 数据文件均为.csv格式,命名规则为`nebdf_{:3.3f}_{:05d}.csv`,其中浮点数部分对应参数(T_f),整数部分对应( ilde{m})。 每个.csv文件包含以下列:transitions(跃迁事件)、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(沿弦路径的距离)、n_intermediates(中间态数目)、deltas(Δ值)、splittings(分裂量)、delta_zeroes(Δ零点)、gammas(γ参数)、PR(PR参数)、glass(玻璃态亚阱采样索引)、omegas1、omegas2、omegasts(分别为第一极小值点、第二极小值点及过渡态附近最低能量路径的曲率)、Index 1、Index 2、Frequency 1>2(1→2跃迁频率)、Frequency 2>1(2→1跃迁频率)、e_1、e_2(两个玻璃态极小值点的单原子能量)、dc(对应(sqrt{dfrac{d^2}{PR}})的典型粒子位移)、Tprep。 其中,glass字段为所采样的玻璃态亚阱的索引;omegas1、omegas2与omegasts分别代表第一极小值、第二极小值与过渡态附近最低能量路径的曲率;e_1与e_2分别为两个玻璃态极小值点的单原子能量;dc为对应(sqrt{dfrac{d^2}{PR}})的典型粒子位移。
