Massless QED_3 with explicit fermions
Dean Lee, Pieter Maris
We study dynamical mass generation in QED in (2+1) dimensions using Hamiltonian lattice methods. We use staggered fermions, and perform simulations with explicit dynamical fermions…
Effect of external magnetic field on electron spin dephasing induced by hyperfine interaction in quantum dots
Y. G. Semenov, K. W. Kim
We investigate the influence of an external magnetic field on spin phase relaxation of single electrons in semiconductor quantum dots induced by the hyperfine interaction. The basi…
First Results from KamLAND: Evidence for Reactor Anti-Neutrino Disappearance
KamLAND Collaboration
KamLAND has been used to measure the flux of 's from distant nuclear reactors. In an exposure of 162 tonyr (145.1 days) the ratio of the number of observed inverse…
Spin-Lattice Relaxation in Si Quantum Dots
B. A. Glavin, K. W. Kim
We consider spin-lattice relaxation processes for electrons trapped in lateral Si quantum dots in a inversion layer. Such dots are characterized by strong confinement in th…
Stability of Standing Accretion Shocks, With an Eye Toward Core Collapse Supernovae
John M. Blondin, Anthony Mezzacappa, Christine DeMarino
We examine the stability of standing, spherical accretion shocks. Accretion shocks arise in core collapse supernovae (the focus of this paper), star formation, and accreting white…
What Can Be Learned with a Lead-Based Supernova-Neutrino Detector?
J. Engel, G. C. McLaughlin, C. Volpe
We examine the prospects for using lead as a supernova-neutrino detector by considering the spectrum of electrons produced, and the number of one- and two-neutron events. We show t…
QCD based quark description of pi-pi scattering up to the sigma and rho region
Stephen R. Cotanch, Pieter Maris
We study forward and backward pi-pi scattering within a QCD model based on the Dyson--Schwinger, Bethe--Salpeter equations truncated to the rainbow-ladder level. Our microscopic re…
BBN And CMB Constraints On Dark Energy
James P. Kneller, Gary Steigman
Current observational data favor cosmological models which differ from the standard model due to the presence of some form of dark energy and, perhaps, by additional contributions…
Meson elastic and transition form factors
Pieter Maris
The Dyson-Schwinger equations of QCD, truncated to ladder-rainbow level, are used to calculate meson form factors in impulse approximation. The infrared strength of the ladder-rain…
Chiral symmetry breaking in (2+1) dimensional QED
Pieter Maris, Dean Lee
We study dynamical mass generation in QED in (2+1) dimensions using Hamiltonian lattice methods. We use staggered fermions, and perform simulations with explicit dynamical fermions…
Zone methods and the fermion sign problem
Dean Lee
We review a recently proposed approach to the problem of alternating signs for fermionic many body Monte Carlo simulations in finite temperature simulations. We derive an estimate…
Facets of confinement and dynamical chiral symmetry breaking
P. Maris, A. Raya, C. D. Roberts +1
The gap equation is a cornerstone in understanding dynamical chiral symmetry breaking and may also provide clues to confinement. A symmetry-preserving truncation of its kernel enab…
Strong Decays of Light Vector Mesons
D. Jarecke, P. Maris, P. C. Tandy
The vector meson strong decays rho-->pi pi, phi-->KK, and K^star-->pi K are studied within a covariant approach based on the ladder-rainbow truncation of the QCD Dyson--Schwinger e…
X-Ray Synchrotron Emitting Fe-Rich Ejecta in SNR RCW 86
Jeonghee Rho, Kristy K. Dyer, Kazimierz J. Borkowski +1
Supernova remnants may exhibit both thermal and nonthermal X-ray emission. We present Chandra observations of RCW 86. Striking differences in the morphology of X-rays below 1 keV a…
Probing Proton Strangeness with Time-Like Virtual Compton Scattering
Stephen R. Cotanch, Robert A. Williams
We document that p(gamma,e+e-)p measurements will yield new, important information about the off-shell time-like nucleon form factors, especially in the phi meson region (q^2 = M^2…
Delayed Nickel Decay in Gamma Ray Bursts
G. C. McLaughlin, R. A. M. J. Wijers
Recently observed emission lines in the X-ray afterglow of gamma ray bursts suggest that iron group elements are either produced in the gamma ray burst, or are present nearby. If t…
Production of UCN by Downscattering in superfluid He4
E. Korobkina, R. Golub, B. W. Wehring +1
Ultra-cold neutrons (UCN) are neutrons with energies so low they can be stored in material bottles and magnetic traps. They have been used to provide the currently most accurate ex…
Off-Axis Neutrino Scattering in GRB Central Engines
Nathan D. George, Arkady Kheyfets, John M. McGhee +1
The search for an understanding of an energy source great enough to explain the gamma-ray burst (GRB) phenomena has attracted much attention from the astrophysical community since…
Active-Sterile Neutrino Conversion: Consequences for the r-Process and Supernova Neutrino Detection
J. Fetter, G. C. McLaughlin, A. B. Balantekin +1
We examine active-sterile neutrino conversion in the late time post-core-bounce supernova environment. By including the effect of feedback on the Mikheyev-Smirnov-Wolfenstein (MSW)…
Dynamic phase transitions in thin ferromagnetic films
Hyunbum Jang, Malcolm J. Grimson, Carol K. Hall
Monte Carlo simulations have been used to investigate the dynamic phase behavior of a classical Heisenberg spin system with a bilinear exchange anisotropy in a planar thin film geo…
Effective masses of diquarks
P. Maris
We study meson and diquark bound states using the rainbow-ladder truncation of QCD's Dyson-Schwinger equations. The infrared strength of the rainbow-ladder kernel is described by t…
ROSAT/Asca Observations of the Mixed-Morphology Supernova Remnant W28
Jeonghee Rho, Kazimierz J. Borkowski
We present ROSAT PSPC and ASCA observations of the supernova remnant (SNR) W28. The overall shape of X-ray emission in W28 is elliptical, dominated by a centrally-concentrated inte…
The Vector Meson Form Factor Analysis in Light-Front Dynamics
Bernard L. G. Bakker, Ho-Meoyng Choi, Chueng-Ryong Ji
