Twisted graphene multilayers provide tunable platforms to engineer flat bands and exploit the associated strongly correlated physics. The two-dimensional nature of these systems makes them suitable for encapsulation by materials that break specific symmetries. In this context, recently discovered two-dimensional helimagnets, such as the multiferroic monolayer NiI2, are specially appealing for breaking time-reversal and inversion symmetries due to their nontrivial spin textures. Here we show…

Giant proximity exchange and flat Chern band in 2D magnet-semiconductor heterostructures
Van der Waals (vdW) heterostructures formed by two-dimensional magnets and semiconductors have provided a fertile ground for fundamental science and for spintronics. We present first-principles


Spin-Split Band Hybridization in Graphene Proximitized with α-RuCl3 Nanosheets.
A low-temperature study of the electronic properties of high quality van der Waals heterostructures composed of a single graphene layer proximitized with α-RuCl3, finding clear evidence for a band realignment that is accompanied by a transfer of electrons originally occupying the graphene's spin degenerate Dirac cones into α- RuCl3 band states with in-plane spin polarization.
Tuning superconductivity in twisted bilayer graphene
This study demonstrates twisted bilayer graphene to be a distinctively tunable platform for exploring correlated states by inducing superconductivity at a twist angle larger than 1.1°—in which correlated phases are otherwise absent—by varying the interlayer spacing with hydrostatic pressure.
Tunable moire spinons in magnetically encapsulated twisted van der Waals quantum spin liquids
Quantum spin-liquid van der Waals magnets such as TaS2, TaSe2, and RuCl3 provide a natural platform to explore new exotic phenomena associated with spinon physics, whose properties can be controlled
Particle-Hole Duality, Emergent Fermi Liquids, and Fractional Chern Insulators in Moiré Flatbands.
This work considers the core problem of Coulomb interactions within fractionally filled spin and valley polarized Moiré flatbands and demonstrates that the dual description in terms of holes, which acquire a nontrivial hole dispersion, provides key physical intuition and enables the use of standard perturbative techniques.
Correlated insulator behaviour at half-filling in magic-angle graphene superlattices
It is shown experimentally that when this angle is close to the ‘magic’ angle the electronic band structure near zero Fermi energy becomes flat, owing to strong interlayer coupling, and these flat bands exhibit insulating states at half-filling, which are not expected in the absence of correlations between electrons.
Spin–orbit correlations and exchange-bias control in twisted Janus dichalcogenide multilayers
Janus dichalcogenide multilayers provide a paradigmatic platform to engineer electronic phenomena dominated by spin–orbit coupling. Their unique spin–orbit effects stem from the mirror symmetry
Unconventional superconductivity in magic-angle graphene superlattices
The realization of intrinsic unconventional superconductivity is reported—which cannot be explained by weak electron–phonon interactions—in a two-dimensional superlattice created by stacking two sheets of graphene that are twisted relative to each other by a small angle.
Layer-dependent ferromagnetism in a van der Waals crystal down to the monolayer limit
Since the discovery of graphene, the family of two-dimensional materials has grown, displaying a broad range of electronic properties. Recent additions include semiconductors with spin–valley
Electrically Controllable Magnetism in Twisted Bilayer Graphene.
This work shows that interaction effects may induce either an antiferromagnetic or a ferromagnetic polarization of AA regions under bias, depending on the electrical bias between layers, which could turn twisted bilayer graphene into an ideal system to study frustrated magnetism in two dimensions.
Superconductors, orbital magnets and correlated states in magic-angle bilayer graphene
This study shows that broken-symmetry states, interaction-driven insulators, orbital magnets, states with non-zero Chern numbers and superconducting domes occur frequently across a wide range of moiré flat band fillings, including close to charge neutrality.
