Dust Formation Above Cool Magnetic Spots in Evolved Stars

Noam Soker, Geoffrey C. Clayton

We examine the structure of cool magnetic spots in the photospheres of evolved stars, specifically asymptotic giant branch (AGB) stars and R Coronae Borealis stars. We find that th…

Measurement of the flux and zenith-angle distribution of upward through-going muons by Super-Kamiokande

Kamiokande Collaboration

A total of 614 upward through-going muons of minimum energy 1.6 GeV are observed by Super-Kamiokande during 537 detector live days. The measured muon flux is 1.74+/-0.07(stat.)+/-0…

A Reanalysis of theUltraviolet Extinction from Interstellar Dust in the Large Magellanic Cloud

K. A. Misselt, Geoffrey C. Clayton, Karl D. Gordon

We have reanalyzed the Large Magellanic Cloud's (LMC) ultraviolet (UV) extinction using data from the IUE final archive. Our new analysis takes advantage of the improved signal--to…

Confinement studies in lattice QCD

Richard W. Haymaker

We describe the current search for confinement mechanisms in lattice QCD. We report on a recent derivation of a lattice Ehrenfest-Maxwell relation for the Abelian projection of SU(…

Evidence for oscillation of atmospheric neutrinos

Kamiokande Collaboration, Y. Fukuda et al

We present an analysis of atmospheric neutrino data from a 33.0 kiloton-year (535-day) exposure of the Super-Kamiokande detector. The data exhibit a zenith angle dependent deficit…

Electric and magnetic U(1) currents in lattice confinement studies

A. Hart, R. W. Haymaker, Y. Sasai

Making use of an Ehrenfest-Maxwell relation we show that in Abelian projected SU(2), in the maximal Abelian gauge, the dynamical electric charge density generated by the coset fiel…

Dynamically generated electric charge distributions in Abelian projected SU(2) lattice gauge theories

A. Hart, R. W. Haymaker, Y. Sasai

We show in the maximal Abelian gauge the dynamical electric charge density generated by the coset fields, gauge fixing and ghosts shows antiscreening as in the case of the non-Abel…

The string tension in the maximally Abelian gauge after smoothing

A. Hart, J. D. Stack, M. Teper

We apply smoothing to SU(2) lattice field configurations in 3+1 dimensions before fixing to the maximally Abelian gauge. The Abelian projected string tension is shown to be stable…

Calibration of Super-Kamiokande Using an Electron Linac

Kamiokande Collaboration

In order to calibrate the Super-Kamiokande experiment for solar neutrino measurements, a linear accelerator (LINAC) for electrons was installed at the detector. LINAC data were tak…

3-manifold invariants and periodicity of homology spheres

Patrick M. Gilmer, Joanna Kania-Bartoszynska, Jozef H. Przytycki

We show how the periodicity of a homology sphere is reflected in the Reshetikhin-Turaev-Witten invariants of the manifold. These yield a criterion for the periodicity of a homology…

Ehrenfest theorems and charge antiscreening in Abelian projected gauge theories

Giuseppe Di Cecio, Alistair Hart, Richard W. Haymaker

We derive exact relations for SU(2) lattice gauge theory in 3+1 dimensions. In terms of Abelian projection, these are the expectation values of Maxwell equations that define a new…

Search for Proton Decay via p -> e+ pi0 in a Large Water Cherenkov Detector

Kamiokande Collaboration, M. Shiozawa

We have searched for proton decay via p -> e+ pi0 using data from a 25.5 kton-year exposure of the Super-Kamiokande detector. We find no candidate events with an expected backgroun…

The Initialization Problem in Quantum Computing

Subhash Kak

The problem of initializing phase in a quantum computing system is considered. The initialization of phases is a problem when the system is initially present in an entangled state…
