    • Reversing entanglement change by a weak measurement 

      Sun, Qingqing; Al-Amri, M.; Davidovich, Luiz; Zubairy, M. Suhail. (American Physical Society, 2010)
      Entanglement of a system changes due to interactions with the environment. A typical type of interaction is amplitude damping. If we add a detector to monitor the environment and only select the no-damping outcome, this ...
    • Reversing the weak measurement of an arbitrary field with finite photon number 

      Sun, Qingqing; Al-Amri, M.; Zubairy, M. Suhail. (American Physical Society, 2009)
      For an arbitrary field with finite photon number inside a leaky cavity, we show that the null-result measurement can be conditionally reversed, using either multiple atoms or a multilevel atom. Even with photons detected, ...
    • Torque magnetometry study of metamagnetic transitions in single-crystal HoNi(2)B(2)C at T approximate to 1.9 K 

      Rathnayaka, K. D. D.; Belevtsev, B. I.; Naugle, Donald G. (American Physical Society, 2007)
      Metamagnetic transitions in single-crystal rare-earth nickel borocarbide HoNi(2)B(2)C have been studied at T approximate to 1.9 K with a Quantum Design torque magnetometer. This compound is highly anisotropic with a variety ...
