spheres.oscillators.spin_osc_map(j, cutoff_dim=None)[source]¶ Construct linear map from spin-j states into the Fock space of the 2D quantum harmonic oscillator.
- Parameters
j (float) – j-value of the spin.
cutoff_dim (int) – Cutoff dimensions of the Fock space.
- Returns
map – Linear map from spin-j Hilbert space to the Fock space of the 2D oscillator.
