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…
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…
Incommensurate magnetism mediated by Weyl fermions in NdAlSi
Jonathan Gaudet, Hung-Yu Yang, Santu Baidya +11
Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect, and negative magnetore…
A structural distortion induced magneto-elastic locking in SrIrO revealed through nonlinear optical harmonic generation
D. H. Torchinsky, H. Chu, L. Zhao +5
We report a global structural distortion in SrIrO using spatially resolved optical second and third harmonic generation rotational anisotropy measurements. A symmetry lower…
A Low Temperature Nonlinear Optical Rotational Anisotropy Spectrometer for the Determination of Crystallographic and Electronic Symmetries
D. H. Torchinsky, H. Chu, T. Qi +2
Nonlinear optical generation from a crystalline material can reveal the symmetries of both its lattice structure and underlying ordered electronic phases and can therefore be explo…
