From: Chiral terahertz wave emission from the Weyl semimetal TaAs

Fig. 4

a–b Time-dependent fitting parameters Cλ, L1λ, L2λ, and Dλ (λ = x, yz) in Eq.  (1). c shows the polarization trajectory (Syz(t), Sx(t)) under elliptically polarized pump light with different θ. The solid and dashed curves represent opposite chiralities.
