A cold dilute atomic gas in an optical resonator can be radiatively cooled by coherent scattering processes when the driving Bike Parts - Seatposts - Rigid laser frequency is tuned close to but below the cavity resonance.When the atoms are sufficiently illuminated, their steady state undergoes a phase transition from a homogeneous distribution to a spatially organized Bragg grating.We characterize the dynamics of this self-ordering process in the semi-classical regime when distinct cavity modes with commensurate wavelengths are quasi-resonantly driven by laser fields via scattering by the atoms.The lasers are simultaneously applied and Neff D65IBE1S0B 60cm Wide Angled Cooker Hood With Perimeter Extractio uniformly illuminate the atoms; their frequencies are chosen so that the atoms are cooled by the radiative processes, and their intensities are either suddenly switched or slowly ramped across the self-ordering transition.Numerical simulations for different ramp protocols predict that the system will exhibit long-lived metastable states, whose occurrence strongly depends on the initial temperature, ramp speed, and the number of atoms.
