One-Dimensional Moir\'e Physics and Chemistry in Heterostrained Bilayer Graphene
, 2023 Twisted bilayer graphene (tBLG) has emerged as a promising platform to explore exotic electronic phases. However, the formation of moir\'e patterns in tBLG has thus far been confined to the introduction of twist angles between the layers.

Highly efficient X-band relativistic twistron
Laser and Particle Beams, 2016 AbstractThe paper proposes a new scheme of high-power microwave oscillator of twistron type using a moderately relativistic high-current electron beam. In numerical experiment using axisymmetric version of the completely electromagnetic PiC code KARAT, a 56% conversion efficiency of electron beam power to electromagnetic radiation was demonstrated ...

Skyrmionic Polarization Textures in Structured Dielectric Planar Media
Nanophotonics, Volume 15, Issue 3, 12 February 2026.Topological 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 ...

Large twisting angles in Bilayer graphene Moire quantum dot structures
, 2021 Recent exploration of the commensurate structure in the turbostratic double layer graphene shows that the large angle twisting can be treated by the decrease of the effective velocity within the energy spectra of the single layer graphene.
