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…
Interlayer-engineering of Charge Order Wave Vector in Kagome Metals
Muntafa M. Mahi, Quazi D. M. Khosru, M. Zahid Hasan +2
Charge orders in the kagome metals AVSb sit at the center of a rich phase diagram that also includes superconductivity, nematicity, and signatures of time-reversal-symmetry…
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…
