sisl (sisl
)¶
sisl is an electronic structure package which may interact with tight-binding and DFT matrices alike.
The full sisl package consistent of a large variety of classes and methods which enables large-scale tight-binding calculations as well as post-processing DFT calculations.
Below a set of classes that are the basis of everything in sisl is present.
Generic classes¶
PeriodicTable |
Periodic table for creating an Atom , or retrieval of atomic information via atomic numbers |
Orbital (R[, q0, tag]) |
Base class for orbital information. |
SphericalOrbital (l, rf_or_func[, q0, tag]) |
An arbitrary orbital class where \(\phi(\mathbf r)=f(|\mathbf r|)Y_l^m(\theta,\varphi)\) |
AtomicOrbital (*args, **kwargs) |
A projected atomic orbital consisting of real harmonics |
Atom (Z[, orbital, mass, tag]) |
Atomic information, mass, name number of orbitals and ranges |
Atoms ([atom, na]) |
A list-like object to contain a list of different atoms with minimum data duplication. |
Geometry (xyz[, atom, sc]) |
Holds atomic information, coordinates, species, lattice vectors |
SuperCell (cell[, nsc, origo]) |
A cell class to retain lattice vectors and a supercell structure |
Grid (shape[, bc, sc, dtype, geometry]) |
Real-space grid information with associated geometry. |
Below are a group of advanced classes rarely needed. A lot of the sub-classes extend these classes, or use them intrinsically. However, they are not necessarily intended for users use.
Advanced classes¶
Quaternion ([angle, v, rad]) |
Quaternion object to enable easy rotational quantities. |
SparseCSR (arg1[, dim, dtype, nnzpr, nnz]) |
A compressed sparse row matrix, slightly different than scipy.sparse.csr_matrix . |
SparseAtom (geometry[, dim, dtype, nnzpr]) |
Sparse object with number of rows equal to the total number of atoms in the Geometry |
SparseOrbital (geometry[, dim, dtype, nnzpr]) |
Sparse object with number of rows equal to the total number of orbitals in the Geometry |
Selector ([routines, ordered]) |
Base class for implementing a selector of class routines |
