    • Experimental Observation and Computational Study of the Spin-gap Excitation in Ba3BiRu2O9 

      Ling, Chris D; Huang, Zixin; Kennedy, Brendan J; Rols, S; Johnson, M R; Zbiri, M; Kimber, S A J; Hudspeth, J; Adroja, D T; Rule, K C; Avdeev, Maxim; Blanchard, Peter E R
      Published 2016
      Ba3BiRu2O9 is a 6H-type perovskite compound containing face-sharing octahedral M2O9 (M = Ir, Ru) dimers, which are magnetically frustrated at low temperatures. On cooling through T∗ = 176 K, it undergoes a pronounced ...

    • Protocols for optical quantum metrology 

      Huang, Zixin
      Published 2018-04-05
      This thesis explores various protocols which can be applied to quantum metrology, such that precision of the measurement can beat the best classical approaches. We first demonstrate that ancilla-assisted schemes can improve ...

    • Tuning the Giant Magnetoelastic Transition in Ba3BiIr2O9 and Ba3BiRu2O9 

      Huang, Zixin; Avdeev, Maxim; Kennedy, Brendan J; Knight, Kevin S; Zhou, Qingdi; Ling, Chris D
      Published 2014
      We have experimentally investigated the effects of pressure on the magnetoelastic transitions associated with the opening of spin-gaps in Ba3BiIr2O9 and Ba3BiRu2O9. For both compounds, reducing the unit cell volume by ...
