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…
Coexistence of High Temperature Superconductivity and Antiferromagnetic Order in a Cuprate with Multiple Hole Fermi Pockets
Xiangyu Luo, Yinghao Li, Hao Chen +23
The intricate relationship between high temperature superconductivity and antiferromagnetic order in cuprates, and the fundamental origin of electron pairing remain open questions.…
p-Wave Orbital Angular Momentum Texture in a Chiral Crystal
Dongjin Oh, Chiara Pacella, Xiangyu Luo +8
The spin and orbital angular momentum (SAM and OAM) are conceptually analogous, yet their roles in condensed matter systems have not been often treated on equal footing. While SAM…
Persistent Fermi Pockets and Robust Electron Pairing in Lightly Doped CuO Planes of Cuprate Superconductors
Hao Chen, Jumin Shi, Yinghao Li +23
High temperature superconductivity in cuprate superconductors is generally considered to be generated from doping the Mott insulators. The fundamental nature of the doped parent co…
