Observation of nonlinear higher-order topological insulators with unconventional boundary truncations
Changming Huang, Alexander V. Kireev, Yuxin Jiang +10
In higher-order topological insulators (HOTIs), topologically nontrivial phases are usually associated with the shift of Wannier centers to topologically nontrivial positions on th…
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…
Thouless pumping of solitons in a nonlocal medium
Fangwei Ye, Aidar H. Ryazhapov, Yaroslav V. Kartashov +1
Thouless pumping is a fundamental phenomenon recognized as being widespread across various areas of physics, with optics holding a particularly prominent role. Here, we study this…
Topological pumping of multi-frequency solitons
Yaroslav V. Kartashov, Fangwei Ye, Vladimir V. Konotop
We report on the topological pumping of quadratic optical solitons, observed through their quantized transport in a dynamic optical potential. A distinctive feature of this system…
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…
