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…
Observation of a structurally driven, reversible topological phase transition in a distorted square net material
Xian P. Yang, Chia-Hsiu Hsu, Gokul Acharya +14
Topological materials hold immense promise for exhibiting exotic quantum phenomena, yet achieving controllable topological phase transitions remains challenging. Here, we demonstra…
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…
Defects Engineering of ZrTe5 for Stabilizing Ideal Topological States
Chia-Hsiu Hsu, Zezhi Wang, Sen Shao +6
ZrTe5 is a highly tunable, high-mobility topological material that hosts a rich variety of quantum phenomena, making it a promising platform for next-generation quantum technologie…
