Fermionic Kaluza-Klein mode mixing in braneworlds
Chun-E Fu, Wen-Xuan Ma
We investigate fermionic Kaluza-Klein (KK) mode mixing in thick braneworld models subjected to generic background perturbations. Conventionally, isolated static backgrounds are com…

Interactions between different Kaluza-Klein modes in brane world
Wen-Xuan Ma, Chun-E Fu
In brane-world theory, through Kaluza-Klein (KK) reduction, a higher-dimensional U(1) gauge field manifests on the brane as a series of vector and scalar KK modes, while a bulk fer…

Kaluza-Klein mode mixing in braneworlds: constraints on scalar absorption and physical degrees of freedom
Wen-Xuan Ma, Chun-E Fu
We investigate the mixing between Kaluza-Klein (KK) modes for a bulk U(1) gauge field within braneworld models. By demanding orthonormality and completeness for the KK basis functi…
