Tailoring photon statistics with an atom-based two-photon interferometer
Martin Cordier, Max Schemmer, Philipp Schneeweiss +2
Controlling the photon statistics of light is paramount for quantum science and technologies. Recently, we demonstrated that transmitting resonant laser light past an ensemble of t…
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…
State-Insensitive Trapping of Alkaline-Earth Atoms in a Nanofiber-Based Optical Dipole Trap
K. Ton, G. Kestler, D. Filin +7
Neutral atoms trapped in the evanescent optical potentials of nanotapered optical fibers are a promising platform for developing quantum technologies and exploring fundamental scie…
Higher-order mean-field theory of chiral waveguide QED
Kasper J. Kusmierek, Sahand Mahmoodian, Martin Cordier +6
Waveguide QED with cold atoms provides a potent platform for the study of non-equilibrium, many-body, and open-system quantum dynamics. Even with weak coupling and strong photon lo…
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…
