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…
Spin nematic liquid crystal and scalar spin chirality in tetragonal lattice YbMnBi
Yaofeng Xie, Sijie Xu, Yu Pan +22
A spin nematic order, analogous to the nematic liquid crystal, characterizes the spontaneous breaking of spin-space rotational symmetry while preserving time-reversal () symmetr…
Quantized Photocurrents in Gapless Topological Matter
Byunghoon Kim, Tenzin Norden, Mohammad Yahyavi +17
The authors experimentally observe a quantized circular photogalvanic effect in the chiral topological semimetal Rh0.95Ni0.05Si, providing an all‑optical analogue of the quantum Ha…
Resilient =3/2 superconductivity in topological semimetal YPtBi
Prathum Saraf, Nicholas A. Crombie, Rahul Sharma +11
Cooper pairing in most of the known fermionic superfluids occurs via spin-1/2 quasiparticle interactions that lead to spin-singlet or spin-triplet pairing. In the topological semim…
Modulation of anomalous Hall angle in a magnetic topological semimetal
Jinying Yang, Yanxing Shang, Xingchen Liu +14
The anomalous Hall angle (θA) is a measure of the efficiency of converting a longitudinal driving current to a transverse spin-polarized Hall current. For anomalous Hall sensing,…
Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator
Jian Tang, Thomas Siyuan Ding, Shuhan Ding +24
Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise…
