Path Integral Lab

Monte Carlo path integral: potentials, ħ, action histogram, phasor sum; click to set endpoints A/B.

About this tool

Path Integral Lab — sample random spacetime paths A→B with action S[path], accumulate phases e^{iS/ħ}, and watch constructive interference near the classical path. Choose free / harmonic / barrier potentials. Click left/right half of the plot to set A or B. Educational cartoon, not lattice QFT.
