qten.ops

Module reference for qten.ops.

ops

Convenience namespace for QTen operation helpers.

This module re-exports commonly used functional operations from geometry, symbolic, band-structure, and point-group modules. It is intended as a compact import surface for workflows that combine several parts of QTen without needing to remember each helper's implementation module.

Geometry operations

• nearest_sites()
• region_tile()
• region_centering()
• center_of_region()
• interstitial_centers()
• get_strip_region_2d()

Fourier and band operations

• fourier_kernel()
• fourier_transform()
• region_restrict()
• interpolate_path()
• upsample()
• svd_projection()

Symbolic operations

• translate_opr()
• rebase_opr()
• fractional_opr()
• region_hilbert()
• hilbert_opr_repr() One-to-one symbolic representation; it cannot express \(SU(2)\) spin mixing.

Point-group operations

• hilbert_repr() Hilbert-space D(g), including the \(SU(2)\) factor on a spinful space.
• joint_point_group_basis()
• point_group_column_symmetrize()
• point_group_operator_symmetrize()
• joint_point_group_column_symmetrize()
• get_direct_transform()

Notes

The full behavioral contracts are documented on the original functions linked above. This module does not wrap or alter the imported functions.
