mindchemistry.e3.o3.su2_generators

mindchemistry.e3.o3.su2_generators(j, dtype=complex64)[source]

Compute the su(2) Lie algebra generators.

Parameters

j (int) – degree of generators.
dtype (dtype) – {complex64, complex128} data type of generators. Default: complex64.

Returns

Tensor, su(2) generators with the dtype is dtype.

Raises

TypeError – If j is not int.

Supported Platforms:: Ascend
