Phononic twisted moire lattice with quasicrystalline patterns

Zihan Jiang et al.

Summary: In this Letter, we demonstrate the existence of point- and loop-shaped localized states induced by flat bands in phononic TMLs with quasicrystalline patterns. Our findings offer a method for manipulating classical waves in various moire structures with quasicrystalline patterns.

On-chip light trapping in bilayer moire photonic crystal slabs

Haoning Tang et al.

Summary: The optical response of bilayer moire photonic structures can be precisely controlled by varying the lattice geometry. These structures exhibit flat bands in the optical band structure with zero group velocity, and they enable momentum-independent light-trapping of Bloch waves in both transverse and vertical directions, resulting in high quality-factors and small mode volumes.

Higher-Order Band Topology in Twisted Moire Superlattice

Bing Liu et al.

Summary: This study predicts the potential existence of a 2D second-order topological insulator in twisted bilayer materials, with unique features such as a non-zero bulk topological index, gapped topological edge states, and in-gap topological corner states. This phenomenon is not only observed in a wide range of twist angles, but also shows robustness to microscopic structure disorder and twist centers, facilitating experimental measurements.

Theory for Twisted Bilayer Photonic Crystal Slabs

Beicheng Lou et al.

Summary: The scattering properties of twisted bilayer photonic crystal slabs were analyzed using a high-dimensional plane wave expansion method, showing strongly tunable resonance properties and chiral behavior. A semi-analytical explanation was provided for the resonant properties, along with a correspondence to a simpler structure.

Flat Bands in Magic-Angle Bilayer Photonic Crystals at Small Twists

Kaichen Dong et al.

Summary: This study utilized a coupled-mode theory to discover magic-angle photonic flat bands with a non-Anderson-type localization in low-angle twisted bilayer honeycomb photonic crystals. It also demonstrated that the interlayer separation can be used as a convenient degree of freedom to tune photonic moire bands without high pressure, providing a new avenue for the development of photonics.

Pseudomagnetic Fields Enabled Manipulation of On-Chip Elastic Waves

Mou Yan et al.

Summary: Researchers demonstrated a method to achieve elastic PMFs in Dirac materials, showing that conical dispersions split into elastic Landau levels in the presence of PMFs and discovering the robust propagation of elastic modes along edges similar to quantum Hall edge transports.

Landau levels in strained two-dimensional photonic crystals

J. Guglielmon et al.

Summary: The primary function of photonic crystals is to engineer the photonic density of states, which regulates light-matter interaction. Strained two-dimensional photonic crystals can generate artificial electric and magnetic fields, leading to highly degenerate Landau levels. Numerical simulations show dispersive Landau levels can be flattened by engineering a pseudoelectric field, providing a design principle for aperiodic nanophotonic systems.
