Emergence of unidirectionality and phase separation in optically dense emitter ensembles
Kasper J. Kusmierek, Max Schemmer, Sahand Mahmoodian +1
The transmission of light through an ensemble of two-level emitters in a one-dimensional geometry is commonly described by one of two emblematic models of quantum electrodynamics (…
Local Measurement Scheme of Gravitational Curvature using Atom Interferometers
Michael Werner, Ali Lezeik, Dennis Schlippert +3
Light pulse atom interferometers (AIFs) are exquisite quantum probes of spatial inhomogeneity and gravitational curvature. Moreover, detailed measurement and calibration are necess…
Squeezing Enhancement in Lossy Multi-Path Atom Interferometers
Julian Günther, Jan-Niclas Kirsten-Siemß, Naceur Gaaloul +1
This paper explores the sensitivity gains afforded by spin-squeezed states in atom interferometry, in particular using Bragg diffraction. We introduce a generalised input-output fo…
Slow Light through Brillouin Scattering in Continuum Quantum Optomechanics
Hashem Zoubi, Klemens Hammerer
We investigate the possibility of achieving a slow signal field at the level of single photons inside nanofibers by exploiting stimulated Brillouin scattering, which involves a str…
Robust double Bragg diffraction via detuning control
Rui Li, V. J. Martínez-Lahuerta, S. Seckmeyer +2
We present a theoretical model and numerical optimization of double Bragg diffraction, a widely used technique in atom interferometry. We derive an effective two-level-system Hamil…
GHZ protocols enhance frequency metrology despite spontaneous decay
Timm Kielinski, Piet O. Schmidt, Klemens Hammerer
The use of correlated states and measurements promises improvements in the accuracy of frequency metrology and the stability of atomic clocks. However, developing strategies robust…
