Fine-Structure Qubit Encoded in Metastable Strontium Trapped in an Optical Lattice

S. Pucher, V. Klüsener, F. Spriestersbach +4

We demonstrate coherent control of the fine-structure qubit in neutral strontium atoms. This qubit is encoded in the metastable and states, couple…

Feedback-cooling the fundamental torsional mechanical mode of a tapered optical fiber to 30 mK

Felix Tebbenjohanns, Jihao Jia, Michael Antesberger +5

Tapered optical fibers (TOFs) are used in many areas of physics and optical technologies ranging from coupling light into nanophotonic components to optical sensing and amplificati…

Observation of superradiant bursts in a cascaded quantum system

Christian Liedl, Felix Tebbenjohanns, Constanze Bach +3

Dicke superradiance describes the collective radiative decay of a fully inverted ensemble of two-level atoms. We experimentally investigate this effect for a chiral, i.e.,~directio…

Collective excitation and decay of waveguide-coupled atoms: from timed Dicke states to inverted ensembles

Christian Liedl, Sebastian Pucher, Felix Tebbenjohanns +2

The collective absorption and emission of light by an ensemble of atoms is at the heart of many fundamental quantum optical effects and the basis for numerous applications. However…

Atomic spin-controlled non-reciprocal Raman amplification of fibre-guided light

Sebastian Pucher, Christian Liedl, Shuwei Jin +2

In a non-reciprocal optical amplifier, gain depends on whether the light propagates forwards or backwards through the device. Typically, one requires either the magneto-optical eff…
