Certifying Nonlocal Spin Quantum Entanglement from Local Tunneling Spectra
Payman Kazemikhah, Ruolun Zhang, Xiangyu Luo +4
Quantum entanglement is intrinsically nonlocal, whereas tunneling spectroscopy measures one site at a time. We show that this apparent mismatch can be overcome: local tunneling spe…
Imaging the topological sign of a Dirac mass with spin-polarized tunneling
Payman Kazemikhah, Ruolun Zhang, Byunghoon Kim +5
A Dirac mass is characterized not only by its magnitude but also by its sign, which influences the Berry curvature, Hall response, and the propagation direction of chiral boundary…
Quantized Photocurrents in Gapless Topological Matter
Byunghoon Kim, Tenzin Norden, Mohammad Yahyavi +17
The quantum Hall effect establishes that topology can fix a material response to integer multiples of fundamental constants when an energy gap isolates the relevant symmetry-protec…
Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
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…
