Loading cold Rb atoms at temperature 120 μK out of a magneto-optical trap (MOT) into a hollow-core photonic crystal fiber (7 μm core diameter) [1] promises interesting scenarios for strong light-atom coupling. To simulate the loading procedure and to optimize the coupling efficiency, we use a 3-dimensional Quantum-Monte-Carlo wave function simulation [2]. In this contribution, we discuss basic aspects of this simulation, modelling Rb atoms as a two-level system. We describe the non-equilibrium relaxation of a thermal ensemble subject to laser cooling in phase space and present results.
