Ground-State Cooling of a Single Atom in a High-Bandwidth Cavity
Eduardo Uruñuela, Wolfgang Alt, Elvira Keiler +4
We report on vibrational ground-state cooling of a single neutral atom coupled to a high-bandwidth Fabry-Pérot cavity. The cooling process relies on degenerate Raman sideband trans…

Non-adiabatic Storage of Short Light Pulses in an Atom-Cavity System
Tobias Macha, Eduardo Uruñuela, Wolfgang Alt +4
We demonstrate the storage of ns light pulses in a single rubidium atom coupled to a fiber-based optical resonator. Our storage protocol addresses a regime beyond the conventio…

Strong Purcell effect on a neutral atom trapped in an open fiber cavity
Jose Gallego, Wolfgang Alt, Tobias Macha +3
We observe a sixfold Purcell broadening of the D line of an optically trapped atom strongly coupled to a fiber cavity. Under external illumination by a near-re…
