Horizontal and Vertical Five-Branes in Heterotic/F-Theory Duality
Bjorn Andreas, Gottfried Curio
We consider the heterotic string on an elliptic Calabi-Yau three-fold with five-branes wrapping curves in the base ('horizontal' curves) of the Calabi-Yau as well as some elliptic…
Chiral Fermions and AdS/CFT Duality for a Nonabelian Orbifold
Paul H. Frampton, T. W. Kephart
We present what we believe is the minimal three-family model compactified on a nonabelian orbifold . Nontrivial irreps of the discrete nonabelian g…
Nonabelian Discrete Symmetries, Fermion Mass Textures and Large Neutrino Mixing
Paul H. Frampton, Andrija Rasin
Nonabelian discrete groups are an attractive tool to describe fermion masses and mixings. They have nonsinglet representations which seem particularly suitable for distinguishing t…
Frobenius splitting of Hilbert schemes of points on surfaces
Shrawan Kumar, Jesper Funch Thomsen
Let X be a quasiprojective smooth surface defined over an algebraically closed field of positive characteristic. We show that if X is Frobenius split then so is the Hilbert scheme…
alpha-decay chains of Z=114, A=289 and Z=118, A=293 in the relativistic mean-field model
M. Bender
A comparison of calculated and experimental Q_alpha values of superheavy even-even nuclei and a few selected odd-N nuclei is presented in the framework of the relativistic mean-fie…
Mode identification from time-resolved spectroscopy of the pulsating white dwarf G 29-38
J. C. Clemens, M. H. van Kerkwijk, Y. Wu
We have used time-resolved spectroscopy to measure the colour dependence of pulsation amplitudes in the DAV white dwarf G 29-38. Model atmospheres predict that mode amplitudes shou…
Surface motion in the pulsating DA white dwarf G 29-38
M. H. van Kerkwijk, J. C. Clemens, Y. Wu
We present time-resolved spectrophotometry of the pulsating DA white dwarf G 29-38. As in previous broad-band photometry, the light curve shows the presence of a large number of pe…
Spectroscopy of Double-Beta and Inverse-Beta Decays from 100Mo for Neutrinos
H. Ejiri, J. Engel, R. Hazama +3
Spectroscopic studies of two beta-rays from 100Mo are shown to be of potential interest for investigating both the Majorana neutrino mass by neutrinoless double beta-decay and low…
A small but nonzero cosmological constant
Y. Jack Ng, H. van Dam
Recent astrophysical observations seem to indicate that the cosmological constant is small but nonzero and positive. The old cosmological constant problem asks why it is so small;…
On Wigner's clock and the detectability of spacetime foam with gravitational-wave interferometers
Y. J. Ng, H. van Dam
A recent paper (gr-qc/9909017) criticizes our work on the structure of spacetime foam. Its authors argue that the quantum uncertainty limit for the position of the quantum clock in…
Vertex Operators for AdS3 Background With Ramond Ramond Flux
Louise Dolan, Edward Witten
In order to study vertex operators for the Type IIB superstring on AdS space, we derive supersymmetric constraint equations for the vertex operators in AdS3xS3 backgrounds with Ram…
Neutralino Inelastic Scattering with Subsequent Detection of Nuclear Gamma Rays
J. Engel, P. Vogel
We consider the potential benefits of searching for supersymmetric dark-matter through its inelastic excitation, via the "scalar current", of low-lying collective nuclear states in…
Shell Corrections of Superheavy Nuclei in Self-Consistent Calculations
A. T. Kruppa, M. Bender, W. Nazarewicz +3
Shell corrections to the nuclear binding energy as a measure of shell effects in superheavy nuclei are studied within the self-consistent Skyrme-Hartree-Fock and Relativistic Mean-…
Pairing Gap and Polarisation Effects
K. Rutz, M. Bender, P. -G. Reinhard +1
The phenomenological adjustment of the nuclear pairing strength is usually performed with respect to the odd-even staggering of the binding energies. We find that the results stron…
Statistical properties of SGR 1900+14 bursts
Ersin Gogus, Peter M. Woods, Chryssa Kouveliotou +4
We study the statistics of soft gamma repeater (SGR) bursts, using a data base of 187 events detected with BATSE and 837 events detected with RXTE PCA, all from SGR 1900+14 during…
Nuclear Octupole Correlations and the Enhancement of Atomic Time-Reversal Violation
J. Engel, J. L. Friar, A. C. Hayes
We examine the time-reversal-violating nuclear ``Schiff moment'' that induces electric dipole moments in atoms. After presenting a self-contained derivation of the form of the Schi…
First principles study of Li intercalated carbon nanotube ropes
Jijun Zhao, Alper Buldum, Jie Han +1
We studied Li intercalated carbon nanotube ropes by using first principles methods. Our results show charge transfer between Li and C and small structural deformation of nanotube d…
Hard Burst Emission from the Soft Gamma Repeater SGR 1900+14
Peter M. Woods, Chryssa Kouveliotou, Jan van Paradijs +7
We present evidence for burst emission from SGR 1900+14 with a power-law high energy spectrum extending beyond 500 keV. Unlike previous detections of high energy photons during bur…
A Search for Chemical Signatures of Galactic Mergers
Inese I. Ivans, Bruce Carney, Luisa de Almeida +1
We present preliminary abundance analyses of a group of high-velocity metal-poor stars. This report describes our work in progress. We examine the derived abundances in the context…
Rigorous estimates of the tails of the probability distribution function for the random linear shear model
J. C. Bronski, R. M. McLaughlin
In previous work Majda and McLaughlin computed explicit expressions for the th moments of a passive scalar advected by a linear shear flow in the form of an integral over ${\bf…
Relativistic Winds from Compact Gamma-ray Sources: I. Radiative Acceleration in the Klein-Nishina Regime
Piero Madau, Christopher Thompson
We consider the radiative acceleration to relativistic bulk velocities of a cold, optically thin plasma which is exposed to an external source of gamma-rays. The flow is driven by…
Physical Mechanisms for the Variable Spin-down of SGR 1900+14
C. Thompson, R. C. Duncan, P. M. Woods +3
We consider the physical implications of the rapid spindown of Soft Gamma Repeater 1900+14, and of the apparent "braking glitch", ΔP/P = l x 10^-4, that was concurrent with the Aug…
Invitation to composition
L. Kluge, E. Paal, J. Stasheff
In 1963 [Ann. of Math. {\bf 78}, 267-288], Gerstenhaber invented a \emph{comp(osition)} calculus in the Hochschild complex of an associative algebra. In this paper, the first steps…
Ununfoldable Polyhedra with Convex Faces
Marshall Bern, Erik D. Demaine, David Eppstein +3
Unfolding a convex polyhedron into a simple planar polygon is a well-studied problem. In this paper, we study the limits of unfoldability by studying nonconvex polyhedra with the s…
