Entanglement propagation through spin chains in the presence of a staggered magnetic field
R. H. Crooks, D. V. Khveshchenko
We study the dynamics of entanglement in the XY spin chain subject to a staggered magnetic field and contrast it to the previously studied uniform field case. We find that, dependi…
Reaction rate uncertainties and 26Al in AGB silicon carbide stardust
M. A. van Raai, M. Lugaro, A. I. Karakas +1
Stardust is a class of presolar grains each of which presents an ideally uncontaminated stellar sample. Mainstream silicon carbide (SiC) stardust formed in the extended envelopes o…
The pulsation modes of the pre-white dwarf PG 1159-035
J. E. S. Costa, S. O. Kepler, D. E. Winget +74
PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…
Accounting for spatial correlation in the scan statistic
Ji Meng Loh, Zhengyuan Zhu
The spatial scan statistic is widely used in epidemiology and medical studies as a tool to identify hotspots of diseases. The classical spatial scan statistic assumes the number of…
Rotation and Macroturbulence in Metal-poor Field Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David F. Gray, David Yong +4
We report the results for rotational velocities, Vrot sin i, and macroturbulence dispersion, zeta(RT), for 12 metal-poor field red giant branch stars and 7 metal-poor field red hor…
Observational Tests of Planet Formation Models
A. Sozzetti, G. Torres, D. W. Latham +8
We summarize the results of two experiments to address important issues related to the correlation between planet frequencies and properties and the metallicity of the hosts. Our r…
Bounds for the covariance of functions of infinite variance stable random variables with applications to central limit theorems and wavelet-based estimation
Vladas Pipiras, Murad S. Taqqu, Patrice Abry
We establish bounds for the covariance of a large class of functions of infinite variance stable random variables, including unbounded functions such as the power function and the…
The Complex Frobenius Theorem for Rough Involutive Structures
C. Denson Hill, Michael Taylor
We establish a version of the complex Frobenius theorem in the context of a complex subbundle S of the complexified tangent bundle of a manifold, having minimal regularity. If the…
Integrability of Rough Almost Complex Structures
C. Denson Hill, Michael Taylor
We extend the Newlander-Nirenberg theorem to manifolds with almost complex structures that have somewhat less than Lipschitz regularity. We also discuss the regularity of local hol…
Upper and Lower Bounds on Gravitational Entropy
Paul H. Frampton, Thomas W. Kephart
The entropy in the interior of the Universe has many contributions including well understood ones from radiation and relic neutrinos. The gravitational entropy is larger and more s…
Current Algebra on the Torus
Louise Dolan, Peter Goddard
We derive the N-point one-loop correlation functions for the currents of an arbitrary affine Kac-Moody algebra. The one-loop amplitudes, which are elliptic functions defined on the…
Rubidium and lead abundances in giant stars of the globular clusters M4 and M5
David Yong, David L. Lambert, Diane B. Paulson +1
We present measurements of the neutron-capture elements Rb and Pb for bright giants in the globular clusters M4 and M5. The clusters are of similar metallicity ([Fe/H] = -1.2) but…
Anatomy of nuclear matrix elements for neutrinoless double-beta decay
Fedor Simkovic, Amand Faessler, Vadim Rodin +2
We show that, within the Quasiparticle Random Phase Approximation (QRPA) and the renormalized QRPA (RQRPA) based on the Bonn CD nucleon-nucleon interaction, the competition between…
Simulating Magnetohydrodynamical Flow with Constrained Transport and Adaptive Mesh Refinement; Algorithms & Tests of the AstroBEAR Code
Andrew J. Cunningham, Adam Frank, Peggy Varniere +2
A description is given of the algorithms implemented in the AstroBEAR adaptive mesh refinement code for ideal magnetohydrodynamics. The code provides several high resolution, shock…
Line Broadening in Field Metal-poor Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David W. Latham, R. P. Stefanik +1
We report 349 radial velocities for 45 metal-poor field red giant and red horizontal branch stars. We have have identified one new spectroscopic binary, HD 4306, and one possible s…
Vanishing Viscosity Limits and Boundary Layers for Circularly Symmetric 2D Flows
M. C. Lopes Filho, A. L. Mazzucato, H. J. Nussenzveig Lopes +1
We continue the work of Lopes Filho, Mazzucato and Nussenzveig Lopes [LMN], on the vanishing viscosity limit of circularly symmetric viscous flow in a disk with rotating boundary,…
Inelastic scattering rates in d-wave superconductors
J. Paaske, D. V. Khveshchenko
The inelastic scattering rates of quasiparticles in a two-dimensional d-wave superconductor, which arise from interactions with either acoustic phonons or other quasiparticles, are…
Young star clusters in M31
Heather Morrison, Nelson Caldwell, Paul Harding +3
In our study of M31's globular cluster system with MMT/Hectospec, we have obtained high-quality spectra of 85 clusters with ages less than 1 Gyr. With the exception of Hubble V, th…
On the structure of Thom polynomials of singularities
L. M. Feher, R. Rimanyi
Thom polynomials of singularities express the cohomology classes dual to singularity submanifolds. A stabilization property of Thom polynomials is known classically, namely that tr…
Random permutations and unique fully supported ergodicity for the Euler adic transformation
Sarah Bailey Frick, Karl Petersen
There is only one fully supported ergodic invariant probability measure for the adic transformation on the space of infinite paths in the graph that underlies the Eulerian numbers.…
Non- and semi-parametric analysis of failure time data with missing failure indicators
Irene Gijbels, Danyu Lin, Zhiliang Ying
A class of estimating functions is introduced for the regression parameter of the Cox proportional hazards model to allow unknown failure statuses on some study subjects. The consi…
