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…
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…
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…
