Coulomb crystallization of xenon highly charged ions in a laser-cooled Ca+ matrix
Leonid Prokhorov, Aaron A. Smith, Mingyao Xu +17
We report on the sympathetic cooling and Coulomb crystallization of xenon highly charged ions (HCIs) with laser-cooled Ca ions. The HCIs are produced in a compact electron beam…
Response Dynamics of Alkali Metal-Noble Gas Hybrid Trispin System
Guobin Liu, Shougang Zhang, Sihong Gu
With numerical calculation of coupled Bloch equations, we have simulated the spin dynamics of nuclear magnetic resonance gyroscope based on alkali metal-noble gas hybrid trispin sy…
Spin noise spectroscopy of a noise-squeezed atomic state
V. Guarrera, R. Gartman, G. Bevilacqua +1
Spin noise spectroscopy is emerging as a powerful technique for studying the dynamics of various spin systems also beyond their thermal equilibrium and linear response. Here, we st…
Linear and non-linear coherent coupling in a Bell-Bloom magnetometer
R. Gartman, V. Guarrera, G. Bevilacqua +1
Spin-exchange collisions in hot vapours are generally regarded as a decoherence mechanism. In contrast, we show that linear and non-linear spin-exchange coupling can lead to the ge…
Parametric amplification and noise-squeezing in room temperature atomic vapours
V. Guarrera, R. Gartman, G. Bevilacqua +2
We report on the use of parametric excitation to coherently manipulate the collective spin state of an atomic vapour at room temperature. Signatures of the parametric excitation ar…
Mesoscopic Rydberg-blockaded ensembles in the superatom regime and beyond
T. M. Weber, M. Höning, T. Niederprüm +6
Controlling strongly interacting many-body systems enables the creation of tailored quantum matter, with properties transcending those based solely on single particle physics. Atom…
A cold-atom random laser
Quentin Baudouin, Nicolas Mercadier, Vera Guarrera +2
Conventional lasers make use of optical cavities to provide feedback to gain media. Conversely, mirrorless lasers can be built by using disordered structures to induce multiple sca…
Continuous Coupling of Ultracold Atoms to an Ionic Plasma via Rydberg Excitation
T. M. Weber, T. Niederprüm, T. Manthey +4
We characterize the two-photon excitation of an ultracold gas of Rubidium atoms to Rydberg states analysing the induced atomic losses from an optical dipole trap. Extending the dur…
