Quantum optics of chiral and antichiral waveguide arrays
Peng Wang, Erik Hiltunen, John C Schotland
We study single-photon scattering by atoms in arrays of one-way waveguides. We investigate both chiral and antichiral arrays, where the one-way waveguides are aligned in the same a…
Optical branched flow in nonlocal nonlinear medium
Tongxun Zhao, Yudian Wang, Ruihan Peng +2
When light propagates through a randomly correlated, slowly varying medium, it generates optical branched flow. Previous studies have demonstrated that the self-focusing effect in…
Topological pumping of light governed by Fibonacci numbers
Ruihan Peng, Kai Yang, Qidong Fu +5
Topological pumping refers to transfer of a physical quantity governed by the systemtopology, resulting in quantized amounts of the transferred quantities. It is a ubiqui-tous wave…
Observation of localization of light in photonic quasicrystals of diverse symmetries
Peng Wang, Qidong Fu, Vladimir V. Konotop +2
Quasicrystals are ubiquitous in nature. Beyond crystalline solids, they can be created as optically induced or technologically fabricated structures in photonic and phononic system…
Observation of Thouless pumping of light in quasiperiodic photonic crystals
Kai Yang, Qidong Fu, Henrique C. Prates +4
Topological transport is determined by global properties of physical media where it occurs and is characterized by quantized amounts of adiabatically transported quantities. Discov…
Observation of period-doubling Bloch oscillations
Naveed Khan, Peng Wang, Qidong Fu +2
Bloch oscillations refer to the periodic oscillation of a wavepacket in a lattice under a constant force. Typically, the oscillation has a fundamental period that corresponds to th…
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…
Two-dimensional nonlinear Thouless pumping of matter waves
Qidong Fu, Peng Wang, Yaroslav V. Kartashov +2
We consider theoretically the nonlinear quantized Thouless pumping of a Bose-Einstein condensate loaded in a two-dimensional dynamical optical lattices. We encountered three differ…
Nonlinear Thouless pumping: solitons and transport breakdown
Qidong Fu, Peng Wang, Yaroslav V. Kartashov +2
One-dimensional topological pumping of matter waves in two overlaid optical lattices moving with respect to each other is considered in the presence of attractive nonlinearity. It…
Optical soliton formation controlled by angle twisting in photonic moiré lattices
Qidong Fu, Peng Wang, Changming Huang +4
Exploration of the impact of synthetic material landscapes featuring tunable geometrical properties on physical processes is a research direction that is currently of great interes…
Localization and delocalization of light in photonic moire lattices
Peng Wang, Yuanlin Zheng, Xianfeng Chen +5
Moire lattices consist of two identical periodic structures overlaid with a relative rotation angle. Present even in everyday life, moire lattices have been also produced, e.g., wi…
