Pythagoras Superposition Principle for Localized Eigenstates of 2D Moiré Lattices
Zixuan Gao, Zhenli Xu, Zhiguo Yang +1
Moiré lattices are aperiodic systems formed by a superposition of two periodic lattices with a relative rotational angle. In optics, the photonic moiré lattice has many appealing p…
Topologically enhanced nonlinear optical response of graphene nanoribbon heterojunctions
Hanying Deng, Zhihao Qu, Yingji He +3
We study the nonlinear optical properties of heterojunctions made of graphene nanoribbons (GNRs) consisting of two segments with either the same or different topological properties…
Observation of linear and nonlinear light localization at the edges of moiré lattices
A. A. Arkhipova, Y. V. Kartashov, S. K. Ivanov +11
We observe linear and nonlinear light localization at the edges and in the corners of truncated moiré lattices created by the superposition of periodic mutually-twisted at Pythagor…
Two-dimensional Thouless pumping of light in photonic moiré lattices
Peng Wang, Qidong Fu, Ruihan Peng +4
Continuous and quantized transports are profoundly different. The latter is determined by the global rather than local properties of a system, it exhibits unique topological featur…
Multi-frequency solitons in commensurate-incommensurate photonic moiré lattices
Yaroslav V. Kartashov, Fangwei Ye, Vladimir V. Konotop +1
We predict that photonic moiré patterns created by two mutually twisted periodic sublattices in quadratic nonlinear media allow the formation of parametric solitons under condition…
Quantum plasmon enhanced nonlinear wave mixing in graphene nanoflakes
Hanying Deng, Changming Huang, Yingji He +1
A distant-neighbor quantum-mechanical method is used to study the nonlinear optical wave mixing in graphene nanoflakes (GNFs), including sum- and difference-frequency generation, a…
