Self-aligning recirculated crossed optical dipole trap for lithium atoms

M Lian, M Mrozek-McCourt, CK Angyal, D Shaddel… - Physical Review A, 2024 - APS
Crossed optical dipole traps (ODTs) provide three-dimensional confinement of cold atoms
and other optically trappable particles. However, the need to maintain the intersection of the …

scaling of large-sample collective decay in inhomogeneous ensembles

S Stryzhenko, A Bruns, T Peters - Physical Review Research, 2024 - APS
We experimentally study collective decay of an extended disordered ensemble of N atoms
inside a hollow-core fiber. We observe up to 300-fold enhanced decay rates, strong optical …

Generation of Narrowband Photon Pairs at High Brightness within a Hollow-Core Fiber

A Bruns - 2023 - tuprints.ulb.tu-darmstadt.de
This research project dealt with the implementation of a non-classical photon-pair source
based on spontaneous four-wave mixing (SFWM) in an ensemble of cold Rubidium atoms …

Experimental set-up for loading Sr atoms into a hollow-core fibre

S Bilicki, M Bober, M Chomski, P Morzynski… - ritschgroup.uibk.ac.at
Many quantum technologies are built around the manipulation of isolated atoms in ultra-high
