Quantum Tunneling
Quantum Tunneling: Penetrating the Impenetrable Barrier Quantum Tunneling: Penetrating the Impenetrable Barrier By Md Irfan | 2nd Year Physics (Hons) Presented on National Science Day – 28th February 2023 Introduction Quantum mechanics has revolutionized our understanding of nature at its most fundamental level. Among its most intriguing consequences is the phenomenon of quantum tunneling —a process that defies classical intuition and permits particles to traverse energy barriers that should be insurmountable. This principle underlies a broad spectrum of physical phenomena, from nuclear fusion in stars to the operation of nanoscale devices, and has far-reaching implications in both theoretical physics and practical technology. Theoretical Foundation: Mathematical Framework Let us examine the situation of a non-relativistic particle of mass m, approaching a potential barrier of height V_0 and width a. Classically, if the energy E Potential Profile \[ V(x...
