Graphene and its chemical derivatives have been a pivotal new class of nanomaterials and
a model system for quantum behavior. The material's excellent electrical conductivity …

This is an introductory review of the physics of topological quantum matter with cold atoms.
Topological quantum phases, originally discovered and investigated in condensed matter …

Kagome-lattices of 3 d-transition metals hosting Weyl/Dirac fermions and topological flat
bands exhibit non-trivial topological characters and novel quantum phases, such as the …

We model the newly synthesized magic-angle-twisted bilayer graphene superconductor with
two px, y-like Wannier orbitals on the superstructure honeycomb lattice, where the hopping …

Inspired by the great development of graphene, more and more research has been
conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D Dirac …

Two-dimensional lattices of coupled micropillars etched in a planar semiconductor
microcavity offer a workbench to engineer the band structure of polaritons. We report …

We report the theoretical discovery of a class of 2D tight-binding models containing nearly
flatbands with nonzero Chern numbers. In contrast with previous studies, where nonlocal …

Compass models are theories of matter in which the couplings between the internal spin (or
other relevant field) components are inherently spatially (typically, direction) dependent. A …

Disclinations—topological defects ubiquitously existing in various materials—can reveal the
intrinsic band topology of the hosting material through the bulk-disclination correspondence …

The extraordinary electronic properties of Dirac materials, the two-dimensional partners of
Weyl semimetals, arise from the linear crossings in their band structure. When the dispersion …
