A Cryogenic Penning Trap Based on Permanent Magnets
F. Völksen, K. K. Anjum, R. P. Czampiel +30
We report on a Penning trap based on NdFeB permanent magnets operated at 4\,K with a magnetic field strength of 280\,mT. Reliable loading and confinement of protons, H ions,…
Chaotic spin dynamics of elongated spinor condensates
Jose Reyes-Calderón, Albert Gallemí, Carsten Klempt +1
Elongated spin- condensates present a highly non-trivial local magnetization dynamics, due to the interplay between nonlinear and quantum effects stemming from the inhomogeneous…
Entanglement-enhanced optical ion clock
Kai Dietze, Lennart Pelzer, Ludwig Krinner +11
Entangled states hold the promise of improving the precision and accuracy of quantum sensors. We experimentally demonstrate that spectroscopy of an optical clock transition using e…
Black Hole Tomography: Unveiling Black Hole Ringdown via Gravitational Wave Observations
A. Ribes Metidieri, B. Bonga, B. Krishnan
During the post-merger regime of a binary black hole merger, the gravitational wave signal consists of a superposition of quasi-normal modes (QNMs) of the remnant black hole. It ha…
Nonlinear ringdown at the black hole horizon
Neev Khera, Ariadna Ribes Metidieri, Béatrice Bonga +6
The gravitational waves emitted by a perturbed black hole ringing down are well described by damped sinusoids, whose frequencies are those of quasinormal modes. Typically, first-or…
Self-probed ptychography from semiconductor high-harmonic generation
Sven Fröhlich, Xu Liu, Aimrane Hamdou +15
We demonstrate a method to image an object using a self-probing approach based on semiconductor high-harmonic generation. On one hand, ptychography enables high-resolution imaging…
LIGOs Quantum Response to Squeezed States
L. McCuller, S. E. Dwyer, A. C. Green +194
Gravitational Wave interferometers achieve their profound sensitivity by combining a Michelson interferometer with optical cavities, suspended masses, and now, squeezed quantum sta…
