Electrified fluctuations in D1⊥D3 and D1⊥D5 systems

We present the physical phenomenon of the subject discussed in the paper [J. Douari, A.H. Ali, Prog. Phys. 3 (2007) 26-32, hep-th/0610288]. In that paper we dealt with the fluctuations of funnel solutions of intersecting D1- and D3-branes and the electric field E was considered as very high value causing the results to be non-physical. In the present work, the variation interval of E is to be [0,1λ[. Then, we extend the study to discuss the overall transverse fluctuations of electrified funnel solutions of D1⊥D5 system in the flat background. The boundary conditions are found to be Neumann boundary conditions.
