Abstract

Nonlinear exciton equations for one- and two-exciton variables, obtained by mapping the two-band model onto the molecular (Frenkel) Hamiltonian, are applied to calculate resonant optical nonlinearities in two-dimensional semiconductors in a strong perpendicular magnetic field. The polarization dependence of the time-resolved four-wave-mixing signals provides a direct probe for the two-exciton manifold as well as for the asymmetry of the particle-particle and particle-hole Coulomb interactions.
