QT Lab

Interactive quantum mechanics wave-function simulator.
New in version 1.0.3
- Fix Infinite Square Well boundaries (x ∈ [-5, 5])
- Correct energy eigenvalues for standing waves
- Add dynamic spatial differentiation for momentum expectation ⟨p⟩
- Add weighted energy expectation ⟨E⟩ for superpositions
- Enhance probability density |ψ|² visuals with shading and legend
- Add Material You dynamic color theming and custom Android 13+ monochrome launcher icons
- Update app name to QT Lab
QT Lab allows students, educators, and physics enthusiasts to explore quantum wave functions through real-time interactive numerical and analytical simulations.

It provides intuition for quantum phenomena—such as wave-packet dispersion, barrier tunneling, harmonic oscillation, and quantum interference—by rendering complex wave functions dynamically.

Features:
* Live Wave Function Visualization: View real and imaginary parts alongside probability density.
* Wave-Function Library: Load textbook cases like Free Gaussian packets, Infinite Wells, and Harmonic Oscillators.
* Interference Workbench: Build custom superpositions and tune amplitudes and phases.
* Material You Integration: Dynamic color theming that adapts to your device's wallpaper (Android 12+).
* 100% Free and Open Source.

Built with Flutter and Material 3.
