Quantum tunneling from a new type of Unified Cantor Potential
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 is characterized by scaling parameter , stage and two real numbers and . For , , the UCP system represents general Cantor potential while for , , this system represent general Smith-Volterra-Cantor (SVC) potential. We provide close-form expression of transmission probability from UCP system for arbitrary and by using -Pochhammer symbol. Several new features of scattering are reported for this system. The transmission probability shows a scaling behavior with 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.
