Limits of Stable Near-Field Probing in Nanophotonic Traps
Johannes Piotrowski, Constanze Bach, Nicolás Vera Paz +2
Near-fields around nanophotonic structures and waveguides can be used to optically interface particles ranging from atoms and molecules to microscopic biological and synthetic part…
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…
Predicting correlations in superradiant emission from a cascaded quantum system
Felix Tebbenjohanns, Christopher D. Mink, Constanze Bach +2
In recent experiments, a novel type of cascaded quantum system has been realized using nanofiber-coupled cold atomic ensembles. This setup has enabled the study of superradiant dec…
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…
Squeezed light from a levitated nanoparticle at room temperature
Lorenzo Magrini, Victor A. Camarena-Chávez, Constanze Bach +2
Quantum measurements of mechanical systems can produce optical squeezing via ponderomotive forces. Its observation requires high environmental isolation and efficient detection, ty…
Real-time optimal quantum control of mechanical motion at room temperature
Lorenzo Magrini, Philipp Rosenzweig, Constanze Bach +6
The ability to accurately control the dynamics of physical systems by measurement and feedback is a pillar of modern engineering. Today, the increasing demand for applied quantum t…
Nanofiber based displacement sensor
Chengjie Ding, Maxime Joos, Constanze Bach +5
We report on the realization of a displacement sensor based on an optical nanofiber. A single gold nano-sphere is deposited on top of a nanofiber and the system is placed within a…
