Recent development in the synthesis of twisted Van der Waals heterostructures [PDF]
Discover NanoTwisted van der Waals (t-vdW) heterostructures (HSs), where the electronic and optical properties can be modulated by the interlayer twist angle, have led to the emerging field of “Twistronics.” By precisely controlling the twist angle in stacked vdW ...

"Tear-And-Stack" Twisted SrTiO<sub>3</sub> Moiré Superlattices for Precise Interfacial Reconstruction and Polar Topology. [PDF]
Adv MaterThe tear‐and‐stack method enables the creation of twisted SrTiO3 bilayers with accurate twist‐angle control, which yield atomically sharp oxide moiré superlattices with emergent exotic topological polar vortices, thereby opening a new pathway for twistronics based on 2D‐like non‐van der Waals oxides.

Atomic frustration-based twistronics [PDF]
2D Materials, 2021 We theoretically investigate atomic frustrated states in diatomic molecules hosted by the bilayer graphene setup twisted by the first magic angle and with broken inversion symmetry in the Dirac cones of the system mini Brillouin zones. Such states show local spectral features typically from uncoupled atoms, but counterintuitively, they also exhibit ...

Quantum Phase Transitions in Graphene Coupled to a Twisted WSe<sub>2</sub> Moiré Ferroelectricity. [PDF]
Adv MaterMoiré ferroelectricity in twisted WSe2 (t‐WSe2) breaks graphene's sublattice symmetry, inducing a room‐temperature metal‐insulator transition. Coupling graphene with ferroelectric domains of t‐WSe2 creates local Dirac points and metallic phases with Fermi‐liquid and non‐Fermi‐liquid behavior.

ARPES Signatures of Few-Layer Twistronic Graphenes
Nano Letters, 2023 Diverse emergent correlated electron phenomena have been observed in twisted graphene layers due to electronic interactions with the moiré superlattice potential. Many electronic structure predictions have been reported exploring this new field, but with few momentum-resolved electronic structure measurements to test them.

Skyrmionic Polarization Textures in Structured Dielectric Planar Media. [PDF]
NanophotonicsTopological skyrmionic textures are typically associated with the structure of optical fields. This work demonstrates that they can also emerge from the optical response of structured metasurfaces. Through engineered light–matter interaction, polarization eigenstates acquire nontrivial topology, which can be mapped into the Chern‐insulator physics ...
