Unique Optical Responses of Weyl Semimetals

The isolation of electrons of different chirality in Weyl semimetals led to predictions of novel transport phenomena. Amongst these are the nonlinear responses and chiral anomaly. Here I will discuss our recent results on a range of Weyl semimetals. First I will focus on their nonlinear responses. Next, I will cover how Raman reveals surprisingly large electron-phonon coupling, that is relevant to their high mobility and potential for chiral transport.
