Mathematical Foundation
In quantum mechanics, barrier penetration, or quantum tunneling, occurs when a particle with energy E passes through a potential barrier of height V (where E < V). The tunneling probability (T) for a rectangular potential barrier is approximated using the Wentzel–Kramers–Brillouin (WKB) method:
T ≈ exp(-2 * ∫κ(x) dx)
where κ(x) = √(2m(V - E))/ħ, m is the particle mass, V is the barrier height, E is the particle energy, ħ is the reduced Planck constant, and the integral is over the barrier width a. For a rectangular barrier, this simplifies to:
T ≈ exp(-2 * a * √(2m(V - E))/ħ)
The calculator converts inputs to SI units, computes the tunneling probability, and expresses it as a percentage, ensuring accuracy based on peer-reviewed quantum mechanical methodologies.
