Abstract

We introduce a new type of potential system that combines the families of general Cantor (fractal system) and general Smith-Volterra-Cantor (non-fractal system) potentials. We call this system as Unified Cantor Potential (UCP) system. The UCP system of total span LL is characterized by scaling parameter ρ>1\rho >1, stage GG and two real numbers α\alpha and β\beta. For α=1\alpha=1, β=0\beta=0, the UCP system represents general Cantor potential while for α=0\alpha=0, β=1\beta=1, this system represent general Smith-Volterra-Cantor (SVC) potential. We provide close-form expression of transmission probability from UCP system for arbitrary α\alpha and β\beta by using qq-Pochhammer symbol. Several new features of scattering are reported for this system. The transmission probability TG(k)T_{G}(k) shows a scaling behavior with kk which is derived analytically for this potential. The proposed system also opens up the possibility for further generalization of new potential systems that encompass a large class of fractal and non-fractal systems. The analytical formulation of tunneling from this system would help to study the transmission feature at breaking threshold when a system transit from fractal to non-fractal domain.
