First-Year Spectroscopy for the SDSS-II Supernova Survey

Kavli Affiliate: Steven Kahn | First 5 Authors: Chen Zheng, Roger W. Romani, Masao Sako, John Marriner, Bruce Bassett | Summary: This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band light curves of supernovae in the redshift range […]

Linear and Nonlinear Optical constants of BiFeO_3

Kavli Affiliate: Darrell Schlom | First 5 Authors: Amit Kumar, R. Rai, Nikolas Podraza, Sava Denev, Mariola Ramirez | Summary: Using spectroscopic ellipsometry, the refractive index and absorption versus wavelength of the ferroelectric antiferromagnet Bismuth Ferrite, BiFeO_3 is reported. The material has a direct band-gap at 442 nm wavelength (2.81 eV). Using optical second harmonic […]

Rank-ordered Multifractal Spectrum for Intermittent Fluctuations

Kavli Affiliate: Tom Chang | First 5 Authors: Tom Chang, Cheng-chin Wu, , , | Summary: We describe a new method that is both physically explicable and quantitatively accurate in describing the multifractal characteristics of intermittent events based on groupings of rank-ordered fluctuations. The generic nature of such rank-ordered spectrum leads it to a natural […]

Nucleosome shape dictates chromatin-fiber structure

Kavli Affiliate: Martin Depken | First 5 Authors: Martin Depken, Helmut Schiessel, , , | Summary: Apart from being the gateway for all access to the eukaryotic genome, chromatin has in recent years been identified as carrying an epigenetic code regulating transcriptional activity. The detailed knowledge of this code contrasts the ignorance of the fiber […]

Conduction Effect of Thermal Radiation in a Metal Shield Pipe in a Cryostat for a Cryogenic Interferometric Gravitational Wave Detector

Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: Takayuki Tomaru, Masao Tokunari, Kazuaki Kuroda, Takashi Uchiyama, Akira Okutomi | Summary: A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational wave detector. The heat load […]

Effects of mode degeneracy in the LIGO Livingston Observatory recycling cavity

Kavli Affiliate: Peter K. Fritschel | First 5 Authors: Andri M. Gretarsson, Erika D’Ambrosio, Valery Frolov, Brian O’Reilly, Peter K. Fritschel | Summary: We analyze the electromagnetic fields in a Pound-Drever-Hall locked, marginally unstable, Fabry-Perot cavity as a function of small changes in the cavity length during resonance. More specifically, we compare the results of […]

Equivariant orbifold structures on the projective line and integrable hierarchies

Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, Hsian-Hua Tseng, , , | Summary: Let $CP^1_{k,m}$ be the orbifold structure on $CP^1$ obtained via uniformizing the neighborhoods of 0 and $infty$ respectively by $zmapsto z^k$ and $wmapsto w^m.$ The diagonal action of the torus on the projective line induces naturally an […]

(21238) 1995 WV7: A New Basaltic Asteroid Outside the 3:1 Mean Motion Resonance

Kavli Affiliate: Geza Gyuk | First 5 Authors: Mark Hammergren, Geza Gyuk, Andrew Puckett, , | Summary: We report visible to near-infrared spectroscopy and spectrophotometry of asteroid (21238) 1995 WV7 that reveal the presence of deep absorption bands indicating a V taxonomic type with an apparently basaltic surface composition. Since this asteroid is on the […]

The spaces of Laurent polynomials, $mathbb{P}^1$-orbifolds, and integrable hierarchies

Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, Hsian-Hua Tseng, , , | Summary: Let $M_{k,m}$ be the space of Laurent polynomials in one variable $x^k + t_1 x^{k-1}+… t_{k+m}x^{-m},$ where $k,mgeq 1$ are fixed integers and $t_{k+m}neq 0$. According to B. Dubrovin cite{D}, $M_{k,m}$ can be equipped with a semi-simple […]

Gromov–Witten Theory of CP^1 and Integrable Hierarchies

Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, , , , | Summary: The ancestor Gromov–Witten invariants of a compact {Kahler} manifold $X$ can be organized in a generating function called the total ancestor potential of $X$. In this paper, we construct Hirota Quadratic Equations (HQE shortly) for the total ancestor […]
