Figure 3.
Simulated SkI (Ω3,t2,Ω1) (panels A–D) and SkIII (Ω3, Ω2, t1) (panels E–H) spectra of a GaAs quantum well, calculated by a mean-field (TDHF) and a higher level (NEE) treatment of electron correlation using XXXX and XRLR pulse polarization configurations, as indicated. The frequency origin is set at the HH exciton energy (eH =1520 meV) along the Ω3 and Ω1 axes, and at twice the HH exciton energy (2eH) along Ω2. Top panels show the simulated linear absorption (solid) and pulse power spectra (dot) used for the computed 2D signals.
