  1. 148. A Quantum Structural Phase Transition in Trapped Ion Crystals

    Invited Speaker / Conférencier(ère) invité(e)

    Arrays of trapped ions offer precise control over both internal quantum states and collective vibrational motion. Here, we demonstrate the manipulation of vibrational modes in ion arrays to drive the 1D linear–2D zigzag quantum structural phase transition. This system provides an intrinsic source of novel entangled states of ion crystal structures, which can be manipulated through trapped ion...

  2. 370. Qutrits and geometric phase via quantum control in ultracold spin-1 systems

    Invited Speaker / Conférencier(ère) invité(e)

    Using the exceptional controllability of an ultracold atoms platform, we explore novel approaches to quantum state preparation and transformation using radio- and microwave-frequency fields. As an introductory example of such state control, we explored a three-level subset of rubidium-87's ground states and created atomic "qutrits," demonstrating the capacity to create arbitrary states, and to...

  3. 436. Uncovering Chemical Reaction Mechanisms in the Ultracold Regime
    Alan Jamison (University of Waterloo)

    Invited Speaker / Conférencier(ère) invité(e)

    At ultracold temperatures, we can exhibit perfect quantum state control of reactants in chemical reactions. Additionally, the strongly-correlated, short-range dynamics of a chemical reaction are dramatically enhanced. This combination of extreme control and added complexity makes a rich arena for exploring chemical dynamics. We report the observation of chemical resonances in both...
