The Lieb lattice and the kagome lattice, which are both well known for their Dirac cones and flat bands, can be continuously converted into each other by a shearing transformation. During this transformation, the flat band is destroyed, but the Dirac cones remain and become tilted, with types...

The layered system LaRu3Si271,72,73,74,75is another good example of a material hosting both a kagome lattice and superconductivity. The structure of LaRu3Si2contains distorted kagome layers of Ru sandwiched between layers of La and layers of Si having a honeycomb structure (see Fig.1e and h...

The intermediate non-Lieb--Mattis ferrimagnetic state occurs irrespective of strip width, which suggests that the intermediate phase of the two-dimensional kagome lattice is also the non-Lieb--Mattis-type ferrimagnetism.doi:10.1143/JPSJ.81.084710Shimokawa, Tokuro...
Interestingly, our findings reveal a distinct pattern of the nonlinear Hall effect in the kagome lattice, where the Berry curvature dipole remains stable when the strength of the staggered hopping varies. This scenario is different from that in the Lieb lattice, where the Berry curvature dipole is...
The model has been shown to host a variety of ordered ground states such as charge density wave (CDW) order and superconductivity on several geometries, including the square, honeycomb, and Lieb lattices. In this work, we study CDW formation in the Holstein model on the kagome lattice, using...
shares the same lattice structure in its inner part with the spatially anisotropic two-dimensional Kagome lattice in which an intermediate phase with a similar behavior is certainly observed, the intermediate phases of these models are the ferrimagnetic one of the unconventional non-Lieb-Mattis type....
