Second Harmonic Generation Spectroscopy of the Surface Charge Density Wave in the Weyl Semimetal CoSi
Awadhesh K. Das, Wesley E. Deeg, Sujan Subedi +3
Using temperature-dependent rotational anisotropy second harmonic generation (RA-SHG), we identify a charge density wave (CDW) instability on the CoSi (001) face with an onset temp…
Evidence for ferroaxial order in 1T-TiSe via elastoresistivity measurements
Qianni Jiang, Ezra Day-Roberts, Benito Gonzalez +5
The study of spontaneous symmetry breaking and electronic order is fundamental in condensed matter physics. Hidden order, symmetry-breaking states that elude conventional probes, p…
Topological spiral magnetism in the Weyl semimetal SmAlSi
Xiaohan Yao Jonathan Gaudet, Rahul Verma, David E. Graf +13
Weyl electrons are intensely studied due to novel charge transport phenomena such as chiral anomaly, Fermi arcs, and photogalvanic effect. Recent theoretical works suggest that Wey…
Mapping Domain Wall Topology in the Magnetic Weyl Semimetal CeAlSi
Yue Sun, Changmin Lee, Hung-Yu Yang +3
We report full vector mapping of local magnetization in CeAlSi, a Weyl semimetal in which both inversion and time-reversal symmetries are broken. The vector maps reveal unanticipat…
Direct Measurement of Helicoid Surface States in RhSi using Nonlinear Optics
Dylan Rees, Baozhu Lu, Yue Sun +6
Despite the fundamental nature of the edge state in topological physics, direct measurement of electronic and optical properties of the Fermi arcs of topological semimetals has pos…
Suppression of second-harmonic generation from linear bands in the topological multifold semimetal RhSi
Baozhu Lu, Sharareh Sayyad, Miguel Ángel Sánchez-MartÍnez +4
Recent experiments in the topological Weyl semimetal TaAs have observed record-breaking second-harmonic generation, a non-linear optical response at generated by an incoming l…
