    • Cavity-enhanced polarization rotation measurements for low-disturbance probing of atoms 

      Mazzinghi, Chiara; Benedicto Orenes, Daniel; Gómez Kabelka, Pau; Lucivero, Vito Giovanni; Aybar, Enes; Gugnani, Stuti; Mitchell, Morgan W. (2021-12-06)
      Article
      Open Access
      We propose and demonstrate cavity-enhanced polarization-rotation measurement as a means to detect magnetic effects in transparent media with greater sensitivity at equal optical disturbance to the medium. Using the Jones ...
    • Long-term laser frequency stabilization using fiber interferometers 

      Kong, Jia; Lucivero, Vito Giovanni; Jiménez-Martínez, Ricardo; Mitchell, Morgan W. (AIP, 2015-07-09)
      Article
      Open Access
      We report long-term laser frequency stabilization using only the target laser and a pair of 5 m fiber interferometers, one as a frequency reference and the second as a sensitive thermometer to stabilize the frequency ...
    • Quantum metrology with high-density atomic vapors and squeezed states of light 

      Lucivero, Vito Giovanni (Universitat Politècnica de Catalunya, 2016-10-14)
      Doctoral thesis
      Open Access
      Nowadays there is a considerable progress in optical magnetometry and spin noise spectroscopy, which use magnetically-sensitive atomic ensembles and optical read-out, approaching the limits set by quantum mechanics. In ...
    • Signal tracking beyond the time resolution of an atomic sensor by Kalman filtering 

      Jimenez Martinez, Ricardo; Kolodynski, Jan; Troullinou, Charikleia; Lucivero, Vito Giovanni; Jong, Kia; Mitchell, Morgan W. (American Institute of Physics (AIP), 2018-01-26)
      Article
      Open Access
      We study causal waveform estimation (tracking) of time-varying signals in a paradigmatic atomic sensor, an alkali vapor monitored by Faraday rotation probing. We use Kalman filtering, which optimally tracks known linear ...
