Book 2018esponds to an entropy-per-molecule entering the quantum degenerate regime and surpasses the so-called percolations threshold where long-range spin propagation is expected..Lastly, this work describes the design, construction, testing, and implementation of a novel apparatus for controlling polar mol

Introduction,ant tool for many-body physics. I then provide a discussion of the context of my thesis and the topics that it includes..Polar molecules are an ideal platform for studying quantum information and quantum simulation due to their long-range dipolar interactions. However, they have many degrees of free

Experimental Background and Overview, have been developed for ultracold atoms, I describe how a molecular quantum gas can be produced. I then describe the first generation JILA KRb apparatus, it’s move into the new X-wing of JILA in 2012, and the laser systems that have been in use on both the first and second generation KRb machines s

Quantum-State Controlled Chemical Reactions and Dipolar Collisions,lear that chemical reactions were responsible for the loss of molecules confined in a conventional far-off-resonance optical dipole trap (Ni et al., Nature 464:1324–1328, 2010; Ospelkaus et al., Science 327(5967):853–857, 2010), as the reaction 2KRb → K. + Rb. is exothermic. For understanding the na

Suppression of Chemical Reactions in a 3D Lattice,experiments, a full 3D optical lattice can be used to pin molecules to individual sites where they will remain without colliding for the duration of the experiment. While research on ultracold polar molecules in optical lattices has started only recently (Chotia et al., Phys Rev Lett 108:080405, 201

A Low-Entropy Quantum Gas of Polar Molecules in a 3D Optical Lattice,an intense effort to further cool the molecular gas, the lowest temperature for the KRb gas reached in a harmonic trap is .∕. = 1. No other groups have produced colder, denser gases to date. As discussed at the end of Chap. ., the best filling fraction we had previously reached in the optical lattic

The New Apparatus: Enhanced Optical and Electric Manipulation of Ultracold Polar Molecules,and addressing. I begin by describing the electrode system, which allows for large, stable, homogeneous electric fields that simultaneously allow arbitrary gradients in two dimensions (2D). I go on to describe how we can couple AC microwave frequencies onto the electrodes to drive rotational transit
