Superconductivity has been observed in moiré systems such as twisted bilayer graphene,
which host flat, dispersionless electronic bands. In parallel, theory work has discovered that …

Together with the development of two-dimensional (2D) materials, transition metal
dichalcogenides (TMDs) have become one of the most popular series of model materials for …

Two-dimensional (2D) material research is rapidly evolving to broaden the spectrum of
emergent 2D systems. Here, we review recent advances in the theory, synthesis …

Stacking orders in 2D van der Waals (vdW) materials dictate the relative sliding (lateral
displacement) and twisting (rotation) between atomically thin layers. By altering the stacking …

Higher-order topological insulators are recently discovered quantum materials exhibiting
distinct topological phases with the generalized bulk-boundary correspondence. T d-WTe2 …

Interacting electrons in one dimension (1D) are governed by the Luttinger liquid (LL) theory
in which excitations are fractionalized. Can a LL-like state emerge in a 2D system as a …

Thermal transport is a fundamental mechanism of energy transfer process quite distinct from
wave propagation phenomena. It can be manipulated well beyond the possibilities offered …

Abstract One-dimensional (1D) interacting electrons are often described as a Luttinger
liquid,,–having properties that are intrinsically different from those of Fermi liquids in higher …

Since the discovery of magic-angle twisted bilayer graphene, flat bands in Dirac materials
have become a prominent platform for realizing strong correlation effects in electronic …

After the preparation of 2D electronic flat band (EFB) in van der Waals (vdW) superlattices,
recent measurements suggest the existence of 1D electronic flat bands (1D‐EFBs) in twisted …
