The destiny of obstructed atomic insulator under correlation
Kun Jiang, Hongming Weng, Jiangping Hu
The obstructed atomic insulators are insulators with both atomic limits and boundary states. In this work, we study the obstructed atomic insulators under correlation. We use the s…
Decoding flat bands from compact localized states
Yuge Chen, Juntao Huang, Kun Jiang +1
The flat band system is an ideal quantum platform to investigate the kaleidoscope created by the electron-electron correlation effects. The central ingredient of realizing a flat b…
Mottness in two-dimensional van der Waals NbX monolayers (X=Cl, Br, and I)
Yi Zhang, Yuhao Gu, Hongming Weng +2
We investigate strong electron-electron correlation effects on 2-dimensional van der Waals materials NbX (X=Cl, Br, I). We find that the monolayers NbX are ideal sy…
Discovery of a Single-Band Mott Insulator in a van der Waals Flat-Band Compound
Shunye Gao, Shuai Zhang, Cuixiang Wang +31
The Mott insulator provides an excellent foundation for exploring a wide range of strongly correlated physical phenomena, such as high-temperature superconductivity, quantum spin l…
Manipulation of Dirac band curvature and momentum-dependent g-factor in a kagome magnet YMn6Sn6
Hong Li, He Zhao, Kun Jiang +7
The Zeeman effect describes the energy change of an atomic quantum state in magnetic field. The magnitude and the direction of this change depend on the dimensionless Lande g-facto…
Anomalous thermal Hall effect and anomalous Nernst effect of CsVSb
Xuebo Zhou, Hongxiong Liu, Wei Wu +6
Motived by time-reversal symmetry breaking and giant anomalous Hall effect in kagome superconductor \textit{A}VSb (\textit{A} = Cs, K, Rb), we carried out the thermal trans…
Charge instability of topological Fermi arcs in chiral crystal CoSi
Zhicheng Rao, Quanxin Hu, Shangjie Tian3 +17
Topological boundary states, emerged at the spatial boundary between topological non-trivial and trivial phases, are usually gapless, or commonly referred as metallic states. For e…
Low-energy effective theory and symmetry classification of flux phases on Kagome lattice
Xilin Feng, Yi Zhang, Kun Jiang +1
Motivated by recent experiments on AVSb (A=K,Rb,Cs), the chiral flux phase has been proposed to explain time-reversal symmetry breaking. To fully understand the physics beh…
Pomeranchuk instability in the nematic phase of two monolayer FeSe/SrTiO3
C. Y. Tang, X. -L. Peng, Y. -H. Yuan +12
Nematicity, where electrons break rotational symmetry while preserving translational symmetry, is ubiquitous in strongly correlated quantum matters, including high-Tc cuprates and…
Correlated insulating phases of twisted bilayer graphene at commensurate filling fractions: a Hartree-Fock study
Yi Zhang, Kun Jiang, Ziqiang Wang +1
Motivated by the recently observed insulating states in twisted bilayer graphene, we study the nature of the correlated insulating phases of the twisted bilayer graphene at commens…
Giant and anisotropic many-body spin-orbit tunability in a strongly correlated kagome magnet
Jia-Xin Yin, Songtian S. Zhang, Hang Li +18
Owing to the unusual geometry of kagome lattices-lattices made of corner-sharing triangles-their electrons are useful for studying the physics of frustrated, correlated and topolog…
Antiferromagnetic Chern insulators in non-centrosymmetric systems
Kun Jiang, Sen Zhou, Xi Dai +1
We investigate a new class of topological antiferromagnetic (AF) Chern insulators driven by electronic interactions in two-dimensional systems without inversion symmetry. Despite t…
Correlation effects and hidden spin-orbit entangled electronic order in parent and electron-doped iridates SrIrO
Sen Zhou, Kun Jiang, Hua Chen +1
Analogs of the high-T cuprates have been long sought after in transition metal oxides. Due to the strong spin-orbit coupling (SOC), the perovskite iridates SrIrO e…
