Effects of electrical charging on the mechanical Q of a fused silica disk

Kavli Affiliate: David H. Shoemaker | First 5 Authors: Michael J. Mortonson, Christophoros C. Vassiliou, David J. Ottaway, David H. Shoemaker, Gregory M. Harry | Summary: We report on the effects of an electrical charge on mechanical loss of a fused silica disk. A degradation of Q was seen that correlated with charge on the […]

A Long Look at NGC 3783 with the XMM-Newton Reflection Grating Spectrometers

Kavli Affiliate: Andrew P. Rasmussen | First 5 Authors: Ehud Behar, Andrew P. Rasmussen, Alexander J. Blustin, Masao Sako, Steven M. Kahn | Summary: A long 280 ks observation of the Seyfert 1 galaxy NGC 3783 with XMM-Newton is reported. We focus on the oxygen line complex between 17 and 24 A as measured with […]

Simple singularities and integrable hierarchies

Kavli Affiliate: Todor E. Milanov | First 5 Authors: Alexander B. Givental, Todor E. Milanov, , , | Summary: The paper math.AG/0108100 gives a construction of the total descendent potential corresponding to a semisimple Frobenius manifold. In math.AG/0209205, it is proved that the total descendent potential corresponding to K. Saito’s Frobenius structure on the parameter […]

Predicting Crystal Structures with Data Mining of Quantum Calculations

Kavli Affiliate: Kristin Persson | First 5 Authors: Stefano Curtarolo, Dane Morgan, Kristin Persson, John Rodgers, Gerbrand Ceder | Summary: Predicting and characterizing the crystal structure of materials is a key problem in materials research and development. It is typically addressed with highly accurate quantum mechanical computations on a small set of candidate structures, or […]
