Exact solution for eigenfunction statistics at the center-of-band anomaly in the Anderson localization model
Exact solution for eigenfunction statistics Anderson localization model
2010/11/24
An exact solution is found for the problem of the center-of-band (E = 0) anomaly in the one-
dimensional (1D) Anderson model of localization. By deriving and solving an equation for the
generating f...
Center vortex model and the G(2) gauge group
QCD phenomenological model center vortex confinement
2011/1/14
The thick center vortex model is applied to G(2) gauge group to obtain the potentials between static sources of the fundamental and adjoint representations.
Binaries migrating in a gaseous disk: Where are the Galactic center binaries?
accretion accretion disks binaries general Galaxy center hydrodynamics methods: numerical
2010/11/9
The massive stars in the Galactic center inner arcsecond share analogous properties with the so-called Hot Jupiters. Most of these young stars have highly eccentric orbits, and were probably not forme...
The Bolocam Galactic Plane Survey IV: 1.1 and 0.35 mm Dust Continuum Emission in the Galactic Center Region
Galactic Plane Survey Galactic Center Region
2010/11/10
The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and com-pared to infrared and radio continuum data. The BG...

Compact formulas guiding-center orbits axisymmetric tokamak geometry
2010/11/16
Compact formulas for trapped-particle and passing-particle guiding-center orbits in axisymmetric tokamak geometry are given in terms of the Jacobi elliptic functions and complete elliptic integrals. ...
Unified treatment of complex and real rotation-angular functions for two-center overlap integrals over arbitrary atomic orbitals

2010/11/12
The new combined formulas have been established for the complex and real rotation-angular functions arising in the evaluation of two-center overlap integrals over arbitrary atomic orbitals in molecula...
A High-Resolution Survey of HI Absorption toward the Central 200 pc of the Galactic Center
High-Resolution Survey Galactic Center
2010/11/10
We present an HI absorption survey of the central 250 pc of the Galaxy. Very Large Array (VLA) observations were made at 21 cm in the DnC and CnB con gurations and have a resolution of 15"(0.6 pc at ...
Properties of local Polyakov loops for SU(2) and SU(3) lattice gauge theory at finite temperature are analyzed. We show that spatial clusters can be identified where the local Polyakov loops have valu...
Massive Star Formation of the Sgr A East HII Regions Near the Galactic Center
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
A group of four compact HII regions associated with the well-known 50 km/s molecular cloud is the closest site of on-going star formation to the dynamical center of the Galaxy, at a projected distance...
The ionized gas at the center of IC 10: A possible localized chemical pollution by Wolf-Rayet stars
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present results from integral field spectroscopy with the Potsdam Multi-Aperture Spectrograph at the 3.5m telescope at Calar Alto Observatory of the intense star-forming region [HL90] 111 at the ce...

Controlling single diamond NV color center photoluminescence spectrum Fabry-Perot microcavity
2010/11/9
We present both theoretical and experimental results on fluorescence of single defect centers in diamond nanocrystals embedded in a planar dielectric microcavity. From a theoretical point of view, we ...
Improving Galactic Center Astrometry by Reducing the Effects of Geometric Distortion
Galaxy Astrophysics (astro-ph.GA)
2010/12/22
We present significantly improved proper motion measurements of the Milky Way's central stellar cluster. These improvements are made possible by refining our astrometric reference frame with a new geo...
Magnetometry of random AC magnetic fields using a single Nitrogen-Vacancy center
Magnetometry random AC magnetic fields single Nitrogen-Vacancy center
2010/10/21
We report on the use of a single NV center to probe fluctuating AC magnetic fields. Using engineered currents to induce random changes in the field amplitude and phase, we show that stochastic fluctua...
Relativistic redshift effects and the Galactic-center stars
Relativistic redshift Galactic-center stars
2010/3/17
The high pericenter velocities (up to a few percent of light) of the S stars around the Galactic-center black hole suggest that general relativistic effects may be detectable through the time variatio...
J/ψ-N center of mass energy dependence of nuclear absorption effect on J/ψ production
xF (or y)-dependence of absorption effect NRQCD model shadowing
2009/12/24
In this paper, the J/ψ nuclear absorption effect is studied at RHIC and LHC energies with the EKS98 shadowing parameterizations. By assuming that the J/ψ absorption cross section, σabs, increases with...
