    • Atomic Bose-Hubbard Systems With Single-Particle Control 

      Preiss, Philipp Moritz (2015-12-14)
      Experiments with ultracold atoms in optical lattices provide outstanding opportunities to realize exotic quantum states due to a high degree of tunability and control. In this thesis, I present experiments that extend this ...
    • Orbital Excitation Blockade and Algorithmic Cooling in Quantum Gases 

      Bakr, Waseem; Preiss, Philipp Moritz; Tai, Ming Eric; Ma, Ruichao; Simon, Jonathan; Greiner, Markus (Nature Publishing Group, 2011)
      Interaction blockade occurs when strong interactions in a confined, few-body system prevent a particle from occupying an otherwise accessible quantum state. Blockade phenomena reveal the underlying granular nature of quantum ...
    • Photon-Assisted Tunneling in a Biased Strongly Correlated Bose Gas 

      Ma, Ruichao; Tai, Ming Eric; Preiss, Philipp Moritz; Bakr, Waseem; Simon, Jonathan; Greiner, Markus (American Physical Society, 2011)
      We study the impact of coherently generated lattice photons on an atomic Mott insulator subjected to a uniform force. Analogous to an array of tunnel-coupled and biased quantum dots, we observe sharp, interaction-shifted ...
    • Quantum Simulation of Antiferromagnetic Spin Chains in an Optical Lattice 

      Simon, Jonathan; Bakr, Waseem S.; Ma, Ruichao; Tai, Ming Eric; Preiss, Philipp Moritz; Greiner, Markus (Nature Publishing Group, 2011)
      Understanding exotic forms of magnetism in quantum mechanical systems is a central goal of modern condensed matter physics, with implications for systems ranging from high-temperature superconductors to spintronic devices. ...
