Geometric Structure of Bell Correlations in Bohmian Mechanics: A Configuration-Space Analysis of EPR Experiments

Tim Dartois, Signe Seidelin, Aurélien Drezet

We develop an explicit configuration-space formulation of EPR-Bell experiments within the framework of de Broglie-Bohm theory, in which joint measurement outcomes arise from a dete…

From Heat Capacity to Coherence in Ultra-Narrow-Linewidth Solid-State Optical Emitters at Sub-Kelvin Temperatures

D Serrano, T Klein, C Marcenat +5

The coherence properties of optical emitters in crystals are crucial for quantum technologies and optical frequency metrology. Cooling to sub-kelvin temperatures can markedly enhan…

Homogeneous Linewidth Behaviour of Narrow Optical Emitters at Sub-kelvin Temperatures

X Lin, M T Hartman, P Goldner +3

We explore the properties of ultra-narrow spectral holes in ensembles of solid-state emitters in crystals over a range of sub-kelvin temperatures, with a focus on their potential a…

Position- and momentum-squeezed quantum states in micro-scale mechanical resonators

Y. Le Coq, K. Mølmer, S. Seidelin

A challenge of modern physics is to investigate the quantum behavior of a bulk material object, for instance a mechanical oscillator. We have earlier demonstrated that by coupling…

Getting the elastic scattering length by observing inelastic collisions in ultracold metastable helium atoms

Signe Seidelin, Rodolphe Hoppeler, Olivier Sirjean +4

We report an experiment measuring simultaneously the temperatureand the flux of ions produced by a cloud of triplet metastablehelium atoms at the Bose-Einstein critical temperature…
