We analyze the structure of supersymmetric Gödel-like cosmological solutions of string theory. Just as the original four-dimensional Gödel universe, these solutions represent rotating, topologically trivial cosmologies with a homogeneous metric and closed timelike curves. First we focus on " phenomenological " aspects of holography, and identify the(More)
Single beam gradient force optical traps, or tweezers, are a powerful tool for a wide variety of experiments in physics, chemistry, and biology. We describe how to build an optical tweezer with a total cost of Ϸ$6500 using only commercially available optics and mounts. We also suggest measurements that could be made using the apparatus.
Quantum annealing is an experimental and potentially breakthrough computational technology for handling hard optimization problems, including problems of computer vision. We present a case study in training a production-scale classifier of tree cover in remote sensing imagery, using early-generation quantum annealing hardware built by D-wave Systems, Inc.(More)
