-enhanced gray-molasses loading and EIT cooling of neutral atoms in nanophotonic traps
Lucas Pache, Antoine Glicenstein, Philipp Schneeweiss +3
Nanophotonic traps for cold atoms typically have trap volumes that are orders of magnitude smaller than, e.g., free-space optical tweezers. This makes efficient loading of these tr…
High-optical-depth, sub-Doppler-width absorption lines at telecom wavelengths in hot, optically driven rubidium vapor
Inna Kviatkovsky, Lucas Pache, Viola-Antonella Zeilberger +4
Doppler broadening presents a major limitation for high-resolution spectroscopy and nonlinear optics in room-temperature atomic vapors. Here, we demonstrate the suppression of Dopp…
Magic-wavelength nanofiber-based two-color dipole trap with sub- spacing
Lucas Pache, Martin Cordier, Hector Letellier +4
We report on the realization and characterization of a novel magic-wavelength nanofiber-based two-color optical dipole trap for cesium that allows us to generate two diametral peri…
State-Insensitive Trapping of Alkaline-Earth Atoms in a Nanofiber-Based Optical Dipole Trap
K. Ton, G. Kestler, D. Filin +7
Neutral atoms trapped in the evanescent optical potentials of nanotapered optical fibers are a promising platform for developing quantum technologies and exploring fundamental scie…
Observation of oscillatory Raman gain associated with two-photon Rabi oscillations of nanofiber-coupled atoms
Christian Liedl, Sebastian Pucher, Philipp Schneeweiss +2
Quantum emitters with a -type level structure enable numerous protocols and applications in quantum science and technology. Understanding and controlling their dynamics is, ther…
Precise Lifetime Measurement of the Cesium State
S. Pucher, P. Schneeweiss, A. Rauschenbeutel +1
We measure the lifetime of the cesium state using a time-resolved single-photon-counting method. We excite atoms in a hot vapor cell via an electric quadrupole transit…
Fictitious magnetic field gradients in optical microtraps as an experimental tool for interrogating and manipulating cold atoms
Bernhard Albrecht, Yijian Meng, Christoph Clausen +3
Optical microtraps provide a strong spatial confinement for laser-cooled atoms. They can, e.g., be realized with strongly focused trapping light beams or the optical near fields of…
Back-Scattering Properties of a Waveguide-Coupled Array of Atoms in the Strongly Non-Paraxial Regime
D. Reitz, C. Sayrin, B. Albrecht +4
We experimentally investigate the back-scattering properties of an array of atoms that is evanescently coupled to an optical nanofiber in the strongly non-paraxial regime. We obser…
State-dependent potentials in a nanofiber-based two-color trap for cold atoms
Fam Le Kien, Philipp Schneeweiss, Arno Rauschenbeutel
We analyze the ac Stark shift of a cesium atom interacting with far-off-resonance guided light fields in the nanofiber-based two-color optical dipole trap realized by Vetsch \texti…
Dynamical polarizability of atoms in arbitrary light fields: general theory and application to cesium
Fam Le Kien, Philipp Schneeweiss, Arno Rauschenbeutel
We present a systematic derivation of the dynamical polarizability and the ac Stark shift of the ground and excited states of atoms interacting with a far-off-resonance light field…
A Nanofiber-Based Optical Conveyor Belt for Cold Atoms
Philipp Schneeweiss, Samuel T. Dawkins, Rudolf Mitsch +3
We demonstrate optical transport of cold cesium atoms over millimeter-scale distances along an optical nanofiber. The atoms are trapped in a one-dimensional optical lattice formed…
