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…
Emergent Quantum-Geometric Equivalence of Injection and Shift Currents
Mohammad Yahyavi, Tay-Rong Chang, Md Shafayat Hossain +3
Injection and shift currents are generally regarded as distinct nonlinear optical responses with separate microscopic origins. Here, we uncover a general hidden connection between…
Interlayer Charge-density-wave Vector Phase Induced Structural Chirality
Sen Shao, Wei-Chi Chiu, Tao Hou +21
Chiral charge density waves (CDWs) have attracted intense interest due to their exotic quantum properties, yet the microscopic origin of structural chirality emerging from correlat…
Wavefunction-Free Approach for Predicting Nonlinear Responses in Weyl Semimetals
Mohammad Yahyavi, Ilya Belopolski, Yuanjun Jin +15
By sidestepping the intractable calculations of many-body wavefunctions, density functional theory (DFT) has revolutionized the prediction of ground states of materials. However, p…
Broken symmetries associated with a Kagome chiral charge order
Zi-Jia Cheng, Md Shafayat Hossain, Qi Zhang +17
Chirality or handedness manifests in all fields of science, ranging from cell biology, molecular interaction, and catalysis to different branches of physics. In condensed matter ph…
