quantax.symmetry.LinearTransform

quantax.symmetry.LinearTransform(matrix: NDArray, center: Sequence[float] | None = None, sector: int = 0, character: Array | None = None) → Symmetry

The symmetry generated by a linear transformation to the lattice.

Parameters:

• matrix – A 2D array for the linear transformation matrix.

• center – The center of the linear transformation.

• sector – The symmetry sector.

• character – The character of the symmetry group elements. This is useful when the symmetry sector doesn’t have a 1D group representation.

Warning

The users are responsible to ensure that the linear transformation generates a symmetry group.
