Fig. 2: Plots of the Bohmian trajectories with k0/σ = 15.
From: Relativistic Bohmian trajectories of photons via weak measurements

In the background of both plots is the quantum-mechanical prediction for the probability density of the particles, ρK(x, t). In (a), the trajectories are completely right-moving and maintain a Gaussian distribution, according to the initial conditions that we have chosen to match the wavefunction density. In (b), we have considered the superposition case, wherein the photon follows a path that matches the interference pattern predicted by ρK(x, t).
