  • Interplay of Electron and Nuclear Spin Noise in n -Type GaAs 
    Berski, Fabian; Hübner, Jens; Oestreich, Michael; Ludwig, Arne; Wieck, A.D.; Glazov, Mikhail (College Park, MD : American Physical Society, 2015)
    We present spin-noise spectroscopy measurements on an ensemble of donor-bound electrons in ultrapure GaAs:Si covering temporal dynamics over 6 orders of magnitude from milliseconds to nanoseconds. The spin-noise spectra ...
  • Optical Amplification of Spin Noise Spectroscopy via Homodyne Detection 
    Sterin, Pavel; Wiegand, Julia; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2018-03-05)
    Spin noise (SN) spectroscopy measurements on delicate semiconductor spin systems, like single (In,Ga) As quantum dots, are currently not limited by optical shot noise but rather by the electronic noise of the detection ...
  • Optical spin noise of a single hole spin localized in an (InGa)as quantum dot 
    Dahbashi, Ramin; Hübner, Jens; Berski, Fabian; Pierz, Klaus; Oestreich, Michael (College Park, MD : American Physical Society, 2014)
    We advance spin noise spectroscopy to the ultimate limit of single spin detection. This technique enables the measurement of the spin dynamic of a single heavy hole localized in a flat (InGa)As quantum dot. Magnetic field ...
  • Spin noise spectroscopy in GaAs 
    Oestreich, Michael; Römer, M.; Haug, Rolf J.; Hägele, D. (College Park, MD : American Physical Society, 2005)
    We observe the noise spectrum of electron spins in bulk GaAs by Faraday-rotation noise spectroscopy. The experimental technique enables the undisturbed measurement of the electron-spin dynamics in semiconductors. We measure ...
  • Ultrahigh bandwidth spin noise spectroscopy: Detection of large g-factor fluctuations in highly-n-doped GaAs 
    Berski, Fabian; Kuhn, Hendrik; Lonnemann, Jan G.; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2013)
    We advance all optical spin noise spectroscopy (SNS) in semiconductors to detection bandwidths of several hundred gigahertz by employing a sophisticated scheme of pulse trains from ultrafast laser oscillators as an optical ...
