Three-dimensional flat Landau levels in an inhomogeneous acoustic crystal
Zheyu Cheng, Yi-jun Guan, Haoran Xue +7
When electrons moving in two-dimensions (2D) are subjected to a strong uniform magnetic field, they form flat bands called Landau levels, which are the basis for the quantum Hall e…
Localization of chiral edge states by the non-Hermitian skin effect
Gui-Geng Liu, Subhaskar Mandal, Peiheng Zhou +11
Quantum Hall systems host chiral edge states extending along the one-dimensional boundary of any two-dimensional sample. In solid state materials, the edge states serve as perfectl…
Topological phenomena at topological defects
Zhi-Kang Lin, Qiang Wang, Yang Liu +4
There are two prominent applications of the mathematical concept of topology to the physics of materials: band topology, which classifies different topological insulators and semim…
On the Electron Pairing Mechanism of Copper-Oxide High Temperature Superconductivity
S. M. O'Mahony, Wangping Ren, Weijiong Chen +6
The elementary CuO2 plane sustaining cuprate high-temperature superconductivity occurs typically at the base of a periodic array of edge-sharing CuO5 pyramids. Virtual transitions…
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…
Observation of dislocation-induced topological modes in a three-dimensional acoustic topological insulator
Haoran Xue, Ding Jia, Yong Ge +6
The interplay between real-space topological lattice defects and the reciprocal-space topology of energy bands can give rise to novel phenomena, such as one-dimensional topological…
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…
Discovery of a Cooper-Pair Density Wave State in a Transition-Metal Dichalcogenide
Xiaolong Liu, Yi Xue Chong, Rahul Sharma +1
Pair density wave (PDW) states are defined by a spatially modulating superconductive order-parameter. To search for such states in transition metal dichalcogenides (TMD) we use hig…
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…
