Magneto-Optical Light-Matter interactions in Weyl Semimetals

Research output: Contribution to journalConference articlepeer-review


We present in this work is an experimental study of topological semimetals. This work was focused on studying the behavior of the type I Co3Sn2S2 Weyl semimetals. Primarily, we are interested in magneto-optical measurements of these materials. Due to the effect of chiral anomaly, it is expected that the angle between electric and magnetic fields due to the term E*B [1] leads to the specific impacts in Weyl semimetals. In particular, it has been claimed that the chiral anomaly results in a charge imbalance between the Weyl nodes. In Weyl semimetals, the dielectric tensor receives a specific form [2] that allows observing chiral anomaly via magneto-optical Kerr effect. Such studies have been performed for Cd3As2 crystals under an external magnetic field, and the outcome of the chiral anomaly was measured by magneto-optical methods. We are demonstrating our first results for Co3Sn2S2 crystals. To the best of our knowledge, such a study was not performed in these materials.
