radtools.SpinHamiltonian.cell

property

property SpinHamiltonian.cell

Unit cell of the lattice.

Returns:

cell(3, 3) numpy.ndarray

Unit cell, rows are vectors, columns are coordinates.

Notes

In order to rotate the cell with an arbitrary rotation matrix \(R\) use the syntax:

rotated_cell = cell @ R.T

Transpose is required, since the vectors are stored as rows.
