| תקציר: | In this talk I will present two laser cooling schemes for trapped particles. In the first part of the talk I will present a cooling scheme that is based on quantum interference and 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. In the second part I will present a cooling scheme which is faster than the trapping frequency which is the uppermost limit of all existing cooling schemes. |
