a Decomposition of the (3, 3) CNT into a spiral of 3-arm sites. b Energies of the KS orbitals. The 402nd is the highest occupied KS orbital. Orbitals with OAM = 0 and ±1 are shown in black and cyan, respectively. c Laser pulses with E0 = 0.5 V/Å, ℏω = 2 eV, and envelope function \(\exp (-{(t-0.3{{{\rm{fs}}}})}^{2}/2{(0.03{{{\rm{fs}}}})}^{2})\) (red) or \(\exp (-{(t-10{{{\rm{fs}}}})}^{2}/2{(3{{{\rm{fs}}}})}^{2})\) (green). The gray curve is \(0.5\sin (\omega t)\). d Normalized Fourier transforms of the curves in c.
