Probing charge pumping and relaxation of the chiral anomaly in a Dirac semimetal
Bing Cheng, Timo Schumann, Susanne Stemmer +1
The linear band crossings of 3D Dirac and Weyl semimetals are characterized by a charge chirality, the parallel or anti-parallel locking of electron spin to its momentum. Such mate…
Efficient Terahertz Harmonic Generation with Coherent Acceleration of Electrons in the Dirac Semimetal Cd3As2
Bing Cheng, Natsuki Kanda, Tatsuhiko N. Ikeda +7
We report strong terahertz (~10^12 Hz) high harmonic generation in thin films of Cd3As2, a three-dimensional Dirac semimetal at room temperature. The third harmonics is detectable…
A Large Effective Phonon Magnetic Moment in a Dirac Semimetal
Bing Cheng, T. Schumann, Y. C. Wang +4
We investigated the magnetoterahertz response of the Dirac semimetal CdAs and observed a particularly low frequency optical phonon, as well as a very prominent and field se…
Magnetoterahertz Response and Faraday Rotation from Massive Dirac Fermions in the Topological Crystalline Insulator PbSnTe
Bing Cheng, P. Taylor, P. Folkes +2
PbSnTe has been shown to be an interesting tunable topological crystalline insulator system. We present a magneto-terahertz spectroscopic study of thin films of Pb$_{0.…
Terahertz conductivity of the magnetic Weyl semimetal MnSn films
Bing Cheng, Youcheng Wang, D. Barbalas +3
MnSn is a non-collinear antiferromagnet which displays a large anomalous Hall effect at room temperature. It is believed that the principal contribution to its anomalous Hall…
