A Turán Theorem for Cayley Graphs
Wei Li, Kai Yang
In this note, we give a Turán theorem for Cayley graphs $\Cay(\Z_p,S)$ over prime cyclic groups . For a graph and a finite abelian group , define the Cayley--Turán num…
Odd cycles in symmetric Cayley graphs on prime cyclic groups
Wei Li, Kai Yang
Let be an odd prime and let be symmetric with . Let $\Cay(\Z_p,S)$ be the undirected Cayley graph on in which and are adjacent if an…
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 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…
