Multi-Overlap Simulations of the Edwards-Anderson Ising Spin Glass
Bernd A. Berg, Wolfhard Janke
We introduce a novel method for numerical spin glass investigations: Simulations of two replica at fixed temperature, weighted such that a broad distribution of the Parisi overlap…
A Measurement of the W Boson Mass
B. Abbott, M. Abolins, B. S. Acharya
We present a measurement of the W boson mass using data collected by the D0 experiment at the Fermilab Tevatron during 1994--1995. We identify W bosons by their decays to fina…
A Measurement of the W Boson Mass
B. Abbott, M. Abolins, B. S. Acharya
We report a measurement of the W boson mass based on an integrated luminosity of 82 pb from \ppbar collisions at TeV recorded in 1994--1995 by the \Dzero dete…
Collective Excitations in High-Temperature Superconductors
M. I. Salkola, J. R. Schrieffer
Collective, low-energy excitations in quasi-two-dimensional d-wave superconductors are analyzed. While the long-range Coulomb interaction shifts the charge-density-wave and phase m…
Static and Dynamical Properties of the Ferromagnetic Kondo Model with Direct Antiferromagnetic Coupling Between the localized Electrons
Seiji Yunoki, Adriana Moreo
The phase diagram of the Kondo lattice Hamiltonian with ferromagnetic Hund's coupling in the limit where the spin of the localized electrons is classical is analyzed in on…
Quenched hadron spectroscopy with improved staggered quark action
MILC Collaboration, Claude Bernard, Tom Blum +9
We investigate light hadron spectroscopy with an improved quenched staggered quark action. We compare the results obtained with an improved gauge plus an improved quark action, an…
Next-to-leading order slepton pair production at hadron colliders
Howard Baer, B. W. Harris, Mary Hall Reno
We compute total cross sections for various slepton pair production reactions in next-to-leading order QCD. For pbarp collisions at root S=2TeV, we find leading order cross section…
Amplitude equations and pattern selection in Faraday waves
Peilong Chen, Jorge Vinals
A nonlinear theory of pattern selection in parametric surface waves (Faraday waves) is presented that is not restricted to small viscous dissipation. By using a multiple scale asym…
Constraints on the Minimal Supergravity Model with Large
Howard Baer, Michal Brhlik, Diego Castano +1
In the minimal supergravity model (mSUGRA), as the parameter increases, the charged Higgs boson and light bottom squark masses decrease, which can potentially increase cont…
Adiabatic reduction near a bifurcation in stochastically modulated systems
Francois Drolet, Jorge Vinals
We re-examine the procedure of adiabatic elimination of fast relaxing variables near a bifurcation point when some of the parameters of the system are stochastically modulated. App…
A quark action for very coarse lattices
M. Alford, Timothy Klassen, Peter Lepage
We investigate a tree-level O(a^3)-accurate action, D234c, on coarse lattices. For the improvement terms we use tadpole-improved coefficients, with the tadpole contribution measure…
Stochastic Hysteresis and Resonance in a Kinetic Ising System
S. W. Sides, P. A. Rikvold, M. A. Novotny
We study hysteresis for a two-dimensional, spin-1/2, nearest-neighbor, kinetic Ising ferromagnet in an oscillating field, using Monte Carlo simulations and analytical theory. Atten…
