Deep‐subwavelength resolution detection of polar magnetization by optical spin meron lattices on hyperbolic metamaterials

Nanophotonics, Volume 14, Issue 24, Page 4323-4331, December 2025.
Abstract Magnetic‐optical Kerr or Faraday effects have been widely used to measure magnetic domain structures by analyzing far‐field polarization properties, with resolution limited by the wavelength scale of light. Here, we propose a methodology to measure the magnetic domain at a deep‐subwavelength scale by investigating the interactions between a ...

Nanoscale Structure and Interfacial Electrochemical Reactivity of Moiré-Engineered Atomic Layers [PDF]

ConspectusThe electronic properties of atomically thin van der Waals (vdW) materials can be precisely manipulated by vertically stacking them with a controlled offset (for example, a rotational offset─i.e., twist─between the layers, or a small difference

Lattice dynamics localization in low-angle twisted bilayer graphene

, 2020
A low twist angle between the two stacked crystal networks in bilayer graphene enables self-organized lattice reconstruction with the formation of a periodic domain.

In situ twistronics of van der Waals heterostructures

, 2020
In van der Waals heterostructures, electronic bands of two-dimensional (2D) materials, their nontrivial topology, and electron-electron interactions can be dramatically changed by a moire pattern induced by twist angles between different layers.

Freespace twistronics for optical supertopologies

Twistronics, the study of moiré superlattices of twisted bilayer 2D materials creating nontrivial physical effects, has recently revolutionized diverse subjects from materials to optoelectronics, nanophotonics, and beyond. Here, breaking the reliance on materials, we present twistronics in higher-dimensional free space, where the twisted lattice is not

Hyperbolic polaritons in twisted β-Ga2O3

npj Nanophotonics
Hyperbolic polaritons (HPs) are essential for integrated photonics due to their directional propagation and strong field confinement. While most research focuses on in-plane light behavior, the out-of-plane features of HPs remain underexplored.
