Atomic-scale Visualization of Electronic Fluid Flow
Xiaolong Liu, Yi Xue Chong, Rahul Sharma +1
The most essential characteristic of any fluid is the velocity field v(r) and this is particularly true for macroscopic quantum fluids. Although rapid advances have occurred in qua…
Scattering Interference Signature of a Pair Density Wave State in the Cuprate Pseudogap Phase
Shuqiu Wang, Peayush Choubey, Yi Xue Chong +6
An unidentified quantum fluid designated as the pseudogap (PG) phase is produced by electron-density depletion in the CuO antiferromagnetic insulator. Current theories suggest…
Severe Dirac Mass Gap Suppression in Sb_2Te_3-based Quantum Anomalous Hall Materials
Yi Xue Chong, Xiaolong Liu, Rahul Sharma +5
Quantum anomalous Hall (QAH) effect appears in ferromagnetic topological insulators (FMTI) when a Dirac mass gap opens in the spectrum of the topological surface states (SS). Unacc…
Imaging Orbital-selective Quasiparticles in the Hund's Metal State of FeSe
Andrey Kostin, Peter O. Sprau, Andreas Kreisel +6
Strong electronic correlations, emerging from the parent Mott insulator phase, are key to copper-based high temperature superconductivity (HTS). By contrast, the parent phase of ir…
