Flatband Line States in Photonic Super-Honeycomb Lattices
Wenchao Yan, Hua Zhong, Daohong Song +5
We establish experimentally a photonic super-honeycomb lattice (sHCL) by use of a cw-laser writing technique, and thereby demonstrate two distinct flatband line states that manifes…
Nonlinear topological photonics
Daria Smirnova, Daniel Leykam, Yidong Chong +1
Rapidly growing demands for fast information processing have launched a race for creating compact and highly efficient optical devices that can reliably transmit signals without lo…
Exciton-Polariton Topological Insulator with an Array of Magnetic Dots
Meng Sun, Dogyun Ko, D. Leykam +2
Recently there have been several proposals on exciton-polariton topological insulators, most requiring strong external magnetic fields induced by bulky superconducting coils. We pr…
Realization of robust boundary modes and non-contractible loop states in photonic Kagome lattices
Jina Ma, Jun-Won Rhim, Liqin Tang +10
Corbino-geometry has well-known applications in physics, as in the design of graphene heterostructures for detecting fractional quantum Hall states or superconducting waveguides fo…
Influence of different disorder types on Aharonov-Bohm caging in the diamond chain
Goran Gligorić, Daniel Leykam, Aleksandra Maluckov
The linear diamond chain with fine-tuned effective magnetic flux has a completely flat energy spectrum and compactly-localized eigenmodes, forming an Aharonov-Bohm cage. We study n…
Topological photonic crystal fibers and ring resonators
Laura Pilozzi, Daniel Leykam, Zhigang Chen +1
We study photonic crystal fibers and ring resonators with topological features induced by Aubry- Andre-Harper modulations of the cladding. We find non trivial gaps and edge states…
Acoustic vortex beams in synthetic magnetic fields
Irving Rondon, Daniel Leykam
We analyze propagation of acoustic vortex beams in longitudinal synthetic magnetic fields. We show how to generate two field configurations using a fluid contained in circulating c…
Universal momentum-to-real-space mapping of topological singularities
Xiuying Liu, Shiqi Xia, Ema Jajtić +7
Topological properties of materials, as manifested in the intriguing phenomena of quantum Hall effect and topological insulators, have attracted overwhelming transdisciplinary inte…
Topological edge states and gap solitons in the nonlinear Dirac model
Daria Smirnova, Lev Smirnov, Daniel Leykam +1
Topological photonics has emerged recently as a novel approach for realizing robust optical circuitry, and the study of nonlinear effects in topological photonics is expected to op…
Photonic Anomalous Quantum Hall Effect
Sunil Mittal, Venkata Vikram Orre, Daniel Leykam +2
We experimentally realize a photonic analogue of the anomalous quantum Hall insulator using a two-dimensional (2D) array of coupled ring resonators. Similar to the Haldane model, o…
Helical transport in coupled resonator waveguides
JungYun Han, Clemens Gneiting, Daniel Leykam
We show that a synthetic pseudospin-momentum coupling can be used to design quasi-one-dimensional disorder-resistant coupled resonator optical waveguides (CROW). In this structure,…
Topological non-Hermitian origin of surface Maxwell waves
Konstantin Y. Bliokh, Daniel Leykam, Max Lein +1
Maxwell electromagnetism, describing the wave properties of light, was formulated 150 years ago. More than 60 years ago it was shown that interfaces between optical media (includin…
