Pauli Matrices.

Constants:

• sigma_x – \(2\times 2\) spin-\(1/2\) Pauli matrix \(\sigma_x\)

• sigma_y – \(2\times 2\) spin-\(1/2\) Pauli matrix \(\sigma_y\)

• sigma_z – \(2\times 2\) spin-\(1/2\) Pauli matrix \(\sigma_z\)

• sigma_vec – The vector of \(2\times2\) Pauli matrices, \(\boldsymbol{\sigma} = (\sigma_x, \sigma_y, \sigma_z)\)

• J_x – \(4\times4\) spin-\(3/2\) Pauli matrix \(J_x\)

• J_y – \(4\times4\) spin-\(3/2\) Pauli matrix \(J_y\)

• J_z – \(4\times4\) spin-\(3/2\) Pauli matrix \(J_z\)

• J_3_x – \(J_x^3\)

• J_3_y – \(J_y^3\)

• J_3_z – \(J_z^3\)

• J_vec – The vector of \(4\times4\) spin-3/2 Pauli matrices, \(\boldsymbol{J} = (J_x, J_y, J_z)\)

• J_3_vec – \(\mathbf {\cal J} = (J_x^3, J_y^3, J_z^3)\)
