Near a magic twist angle, bilayer graphene transforms from a weakly correlated Fermi liquid
to a strongly correlated two-dimensional electron system with properties that are …

As the dimensions of a material shrink from an extended bulk solid to a nanoscale structure,
size and quantum confinement effects become dominant, altering the properties of the …

We propose magic-angle helical trilayer graphene (HTG), a helical structure featuring
identical rotation angles between three consecutive layers of graphene, as a unique and …

Mechanical deformation of a crystal can have a profound effect on its physical properties.
Notably, even small modifications of bond geometry can completely change the size and …

Electronic flat-band materials host quantum states characterized by a quenched kinetic
energy. These flat bands are often conducive to enhanced electron correlation effects and …

Moiré heterobilayer transition metal dichalcogenides (TMDs) emerge as an ideal system for
simulating the single-band Hubbard model and interesting correlated phases have been …

Moiré systems have emerged in recent years as a rich platform to study strong correlations.
Here, we will propose a simple, experimentally feasible setup based on periodically strained …

Two-dimensional magnets and superconductors are emerging as tunable building-blocks
for quantum computing and superconducting spintronic devices, and have been used to …

The exceptional control of the electronic energy bands in atomically thin quantum materials
has led to the discovery of several emergent phenomena. However, at present there is no …

Despite the potential of graphene for building a variety of quantum photonic devices, its
centrosymmetric nature forbids the observation of second harmonic generation (SHG) for …
