This code provides tools to trace the ray trajectories for Bogoliubov excitations on top of a polariton vortex flow. The mean field quantities are generated with ddGPE simulations. These rays are derived using a Hamiltonian description within the framework of the WKB approximation.
disp.py: Visualizes the dispersion curves for Bogoliubov excitations.rays_tracing.py: Computes the trajectories for given initial conditions and plots/saves the results.
