### **Card Description for Dataset** |
|
|
|

|
|
|
**Dataset Name:** Atomic Structures and H/S Matrices of aBN Configurations |
|
**Description:** |
|
This dataset contains computationally generated atomic structures of amorphous boron nitride (aBN) with various configurations containing 2, 3, 8, 32, and 64 atoms per unit. Each structure is described by its atomic positions, lattice properties, and associated Hamiltonian (H) and overlap (S) matrices, which are commonly used in quantum mechanical simulations and electronic structure calculations. |

**Features:** |
|
1. **nr_atoms:** Number of atoms in the structure (2, 3, 8, 32, 64). |
|
2. **atomic_types_z:** Atomic types represented by their atomic numbers. |
|
3. **atomic_positions:** Cartesian coordinates of the atoms. |
|
4. **lattice_nsc:** Lattice scaling factors. |
|
5. **lattice_origin:** Origin of the lattice system. |
|
6. **lattice_vectors:** Lattice vectors defining the cell geometry. |
|
7. **boundary_condition:** Boundary conditions applied to the system (e.g., periodic). |
|
8. **h_matrix:** Hamiltonian matrix representing the quantum mechanical interactions. |
|
9. **s_matrix:** Overlap matrix describing the basis set overlap. |

|
**Splits:** |
|
The dataset is organized into splits based on the number of atoms per structure: |
|
- `nr_atoms_2` |
|
- `nr_atoms_3` |
|
- `nr_atoms_8` |
|
- `nr_atoms_32` |
|
- `nr_atoms_64` |
|
|
|
Each split corresponds to structures with the specified number of atoms, enabling targeted analysis or model training. |
