    Optimal Cold Atom Thermometry Using Adaptive Bayesian Strategies by Jonas Glatthard, Jesús Rubio, Rahul Sawant, Thomas Hewitt, Giovanni Barontini, Luis A. Correa

    Published 2022-12-01
    “…Specifically, we process data from real and simulated release-recapture thermometry experiments on few potassium atoms cooled down to the microkelvin range in an optical tweezer. From simulations, we demonstrate that adaptively choosing the release-recapture times to maximize information gain does substantially reduce the number of measurements needed for the estimate to converge to a final reading. …”

    Sensing directional noise baths in levitated optomechanics by J. M. H. Gosling, A. Pontin, J. H. Iacoponi, P. F. Barker, T. S. Monteiro

    Published 2024-01-01
    “…However, the possibility of searching for a stochastic stream of weak impulses, or more generally a directional broadband signal, need not be excluded; with this and other applications in mind, we apply Gaussian white noise impulses with a well defined direction Ψ to a levitated nanosphere trapped and 3D cooled in an optical tweezer. We find that cross-correlation power spectra offer a calibration-free distinctive signature of the presence of a directional broadband force and its orientation quadrant, unlike normal power spectral densities (PSDs). …”
