How to Use

  1. Select quantum system type (particle-in-a-box, hydrogen atom, tunneling, or harmonic oscillator) from the cat-filter dropdown
  2. Input physical parameters: particle mass (electron = 9.109e-31 kg), potential well width (0.1–10 nm), or barrier height (1–100 eV)
  3. Run simulation to compute energy eigenvalues, wavefunctions, and probability densities; export CSV data for spectroscopy validation

Worked Example

Electron confined in infinite square well of width L = 2 nm: ground state energy E1 = h²/(8mL²) = (6.626e-34)²/(8 × 9.109e-31 × (2e-9)²) = 0.151 eV. First excited state E2 = 4E1 = 0.604 eV. Transition photon wavelength λ = hc/(E2−E1) = 1.236e-6 m = 1.236 μm (infrared), matching near-IR absorption in quantum dot nanocrystals used in photovoltaic devices.
