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…

Spontaneous Symmetry Breaking In Nonlinear Binary Periodic Systems
Ruihan Peng, Qidong Fu, Yejia Chen +3
Spontaneous symmetry breaking (SSB) occurs when modes of asymmetric profile appear in a symmetric, double-well potential, due to the nonlinearity of the potential exceeding a criti…
