-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…
Hybrid Trapping of Cold Atoms with Surface Forces and Blue-Detuned Evanescent Light on a Nanophotonic Waveguide
Riccardo Pennetta, Antoine Glicenstein, Philipp Schneeweiss +2
We demonstrate a novel hybrid nanophotonic trap for cold neutral atoms, leveraging surface forces for attraction and blue-detuned evanescent light for repulsion. We attribute the a…
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…
Simple analytical model describing the collective nonlinear response of an ensemble of two-level emitters weakly coupled to a waveguide
Max Schemmer, Martin Cordier, Lucas Pache +3
We model and investigate the collective nonlinear optical response of an ensemble of two-level emitters that are weakly coupled to a single-mode waveguide. Our approach generalizes…
Photon Transport in a Gas of Two-Level Atoms: Unveiling Quantum Light Creation
Leonid Yatsenko, Martin Cordier, Lucas Pache +4
We present a theoretical analysis of nearly monochromatic light propagation through a gas of two-level atoms using the Heisenberg-Langevin equation method. Our focus is on the evol…
