Fig. 3: Floquet spectrum and orbital texture.

Spectral function A(k, ω) in the presence of a driving laser, associated spectral function A_2,0(k, ω) projected onto \((\ell ,m)=(2,0)\equiv {d}_{{z}^{2}}\) orbitals, and orbital angular momentum texture ℓ_z(k, ω) defined by Eq. (7), for (a) E₀ = 1.0 × 10⁻³ a.u., and (b) E₀ = 2.0 × 10⁻³ a.u. peak pump field strength. The pump photon energy is ℏω_p = 1.4 eV and the pump field is left-handed circularly polarized.
