Module spinor_rotation_3d

Three-dimensional rotations of spinors.

Enums

SpinConstraint

Enumerated type to manage spin constraints and spin space information for the conventional treatment of spin and spatial degrees of freedom in a decoupled manner.

SpinOrbitCoupled

Enumerated type to manage spin–orbit-coupled layout in the coupled treatment of spin and spatial degrees of freedom.

Traits

StructureConstraint

Trait for defining the spin-spatial structure of the coefficient matrices.
