Fast and Robust Laser Cooling of Trapped Systems — •Javier Cerrillo Moreno — Inst. for Mathematical Sciences, Imperial College, London, UK — Quantum Optics and Laser Science group, Imperial College, London, UK — Inst. für Theoretische Physik, Universität Ulm, Germany

We present a robust and fast laser cooling scheme suitable for trapped ions, atoms or cantilevers. Based on quantum interference, generated by a special laser configuration, it is able to rapidly cool the system such that the final phonon occupation vanishes to zeroth order in the Lamb-Dicke parameter in contrast to existing cooling schemes. Furthermore, it is robust under conditions of fluctuating laser intensity and frequency, thus making it a viable candidate for experimental applications.
