Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

The recent discovery of the A V3Sb5 (A= K, Rb, Cs) kagome superconductors launched a
growing field of research investigating the interplay between superconductivity and charge …

The recent discovery of a charge density (CDW) state in ScV 6 Sn 6 at T CDW= 91 K offers
new opportunities to understand the origins of electronic instabilities in topological kagome …

Flat band systems are currently under intense investigation in quantum materials, optical
lattices, and metamaterials. These efforts are motivated by potential realization of strongly …

In condensed matter physics, the Kagome lattice and its inherent flat bands have attracted
considerable attention for their prediction and observation to host a variety of exotic physical …

Flat electronic bands are expected to show proportionally enhanced electron correlations,
which may generate a plethora of novel quantum phases and unusual low-energy …

Materials hosting flat bands at the vicinity of the Fermi level promote exotic symmetry broken
states. Common to many of these are van Hove singularities at saddle points of the …

We explore the electronic and structural properties of F m 3¯ m Lu-HN structures with
specific N, H ordering due to their remarkably narrow hydrogen-based bands at the Fermi …

'Strange'metals that do not follow the predictions of Fermi liquid theory are prevalent in
materials that feature superconductivity arising from electron interactions. In recent years, it …

The saddle point (Van Hove singularity) exhibits a divergent density of states in two-
dimensional systems, leading to fascinating phenomena such as strong correlations and …
