Strong interlayer coupling and stable topological flat bands in twisted bilayer photonic Moire superlattices
Chang-Hwan Yi, Hee Chul Park, Moon Jip Park
The moiré superlattice of misaligned atomic bilayers paves the way for designing a new class of materials with wide tunability. In this work, we propose a photonic analog of the mo…
Disorder-driven Phase Transitions of Second-order Non-Hermitian Skin Effects
Kyoung-Min Kim, Moon Jip Park
Non-Hermitian skin effect exhibits the collapse of the extended bulk modes into the extensive number of localized boundary states in open boundary conditions. Here we demonstrate t…
Length scale formation in the Landau levels of quasicrystals
Junmo Jeon, Moon Jip Park, SungBin Lee
Exotic tiling patterns of quasicrystals have motivated extensive studies of quantum phenomena such as critical states and phasons. Nevertheless, the systematic understanding of the…
Hinge Magnons from Non-collinear Magnetic Order in Honeycomb Antiferromagnet
Moon Jip Park, SungBin Lee, Yong Baek Kim
We propose that non-collinear magnetic order in quantum magnets can harbor a novel higher-order topological magnon phase with non-Hermitian topology and hinge magnon modes. We cons…
