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 …

Twisted interfaces between stacked van der Waals (vdW) cuprate crystals present a platform
for engineering superconducting order parameters by adjusting stacking angles. Using a …

We show that bilayer graphene in the presence of a 2D superlattice potential provides a
highly tunable setup that can realize a variety of flat band phenomena. We focus on two …

Twisted van der Waals (vdW) heterostructures offer a unique platform for engineering the
efficient Josephson coupling between cuprate thin crystals harboring the nodal …

We show that interlayer current induces topological superconductivity in twisted bilayers of
nodal superconductors. A bulk gap opens and achieves its maximum near a “magic” twist …

We employ analytical and numerical approaches to show that unpaired Majorana zero
modes can occur in cores of Abrikosov vortices at the interface between a three-dimensional …

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 …

The lowest-order Josephson coupling, J 1 (θ) cos (ϕ), between two d-wave superconductors
with a phase difference ϕ across the junction vanishes when their relative orientation is …

Fractal Hofstadter bands have become widely accessible with the advent of moiré
superlattices, opening the door to studies of the effect of interactions in these systems. In this …

Bernal stacked bilayer graphene subject to a superlattice potential can realize topological
and stacked flat bands [Ghorashi, Phys. Rev. Lett. 130, 196201 (2023) …
