【 摘 要 】

We predict nonlinear optical polarization rotation in two-dimensional massless Dirac systems including graphene and 8-Pmmn. borophene. When illuminated, a continuous-wave optical field leads to a nonlinear steady state of photoexcited carriers in the medium. The photoexcited population inversion and the interband coherence give rise to a finite transverse optical conductivity sigma(xy)(omega). This in turn leads to definitive signatures in associated Kerr and Faraday polarization rotation, which are measurable in a realistic experimental scenario.
