A polarized high-field infrared instrument reveals giant infrared chirality in Weyl semimetals
Zhi-Ming Yu, Yugui YaoThis highlight introduces the work of Yuan et al., who observed the giant broadband infrared circular dichroism in the type-II Weyl semimetal Mn(Bi1-xSbx)2Te4 for the first time through the development of a high-field magneto-infrared spectroscopy system with polarization resolution.
