Fig. 8: Twisted light to twisted exciton.
From: Conversion of twisted light to twisted excitons using carbon nanotubes
Exciton populations in a 4 nm long (3, 3) CNT illuminated by a twisted light pulse with PAM = −1 (p1, p7), 0 (p2), or 1 (p3, p8), twisted light pulses with PAM = −1 and 1 of the same amplitude (p4), twisted light pulses with PAM = −1, 0, and 1 of the same amplitude (p5), and two twisted light pulses with PAM = −1 of the same amplitude (p6). The CNT is initially in the ground state for p1 to p6 and in a 0.95:0.05 superposition of the ground state and excited states for p7 and p8.
