Emergence of second-order coherence in superfluorescence
Constanze Bach, Felix Tebbenjohanns, Christian Liedl +2
We experimentally investigate the second-order quantum coherence function of a superradiant burst in a cascaded quantum system. We chirally (i.e. direction-dependently) couple roug…
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…
Observation of oscillatory Raman gain associated with two-photon Rabi oscillations of nanofiber-coupled atoms
Christian Liedl, Sebastian Pucher, Philipp Schneeweiss +2
Quantum emitters with a -type level structure enable numerous protocols and applications in quantum science and technology. Understanding and controlling their dynamics is, ther…
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…
Bragg condition for scattering into a guided optical mode
B. Olmos, C. Liedl, I. Lesanovsky +1
We theoretically investigate light scattering from an array of atoms into the guided modes of a waveguide. We show that the scattering of a plane wave laser field into the waveguid…
