Improved Search for (nu)over-bar(mu) -> (nu)over-bar(e) Oscillations in the MiniBooNE Experiment
(American Physical Society, 2013-04-15)
The MiniBooNE experiment at Fermilab reports results from an analysis of (nu)overbar(e) appearance data from 11.27 X 10(20) protons on target in the antineutrino mode, an increase of approximately a factor of 2 over the ...
Predictions of m(b)/m(tau) and m(t) in an asymptotically nonfree theory

Time-resolved differential transmission in MOVPE-grown ferromagnetic InMnAs
(American Physical Society, 2012-03-27)
We measured time-resolved differential transmission in InMnAs for different pump/probe schemes as a function of temperature, laser fluence, and external magnetic field. We observed tunability of the carrier relaxation time. ...
Electronic and quantum phase coherence properties of bismuth thin films
(AIP Publishing, 2012-06)
We present a method to deposit bulk-like Bi films by thermal evaporation and study the electrical, quantum coherence, and physical properties. A two stage growth procedure was found to optimize the film properties, with ...
Measurement of the spectral momentum distribution of valence-electrons in amorphous-carbon by (e, 2e) spectroscopy
(American Physical Society, 1994-01-15)
The spectral momentum density of the valence band of are evaporated amorphous carbon has been measured by (e, 2e) spectroscopy with significantly improved energy resolution relative to earlier studies. The valence band has ...
Percolation-enhanced supersolids in the extended Bose-Hubbard model
(American Physical Society, 2012-01-04)
We theoretically study the stability of lattice supersolid states in the extended Bose-Hubbard model with bounded spatial disorder. We construct a disorder mean-field theory and compare with quantum Monte Carlo calculations. ...
Time resolved magneto-optical studies of ferromagnetic InMnSb films
(AIP Publishing, 2008-02)
We report time resolved magneto-optical measurements in InMnSb ferromagnetic films with 2% and 2.8% Mn contents grown by low temperature molecular beam epitaxy. In order to probe a possible interaction between the spins ...
Critical dynamics at incommensurate phase transitions and NMR relaxation experiments
(Amer Physical Soc, 1999-05-01)
We study the critical dynamics of crystals which undergo a second-order phase transition from a high-temperature normal phase to a structurally incommensurate (IC) modulated phase. We give a comprehensive description of ...
Spatial Variability Enhances Species Fitness in Stochastic Predator-Prey Interactions
(American Physical Society, 2008-12-19)
We study the influence of spatially varying reaction rates on a spatial stochastic two-species Lotka-Volterra lattice model for predator-prey interactions using two-dimensional Monte Carlo simulations. The effects of this ...
Comparison of the calorimetric and kinematic methods of neutrino energy reconstruction in disappearance experiments
(Amer Physical Soc, 2015-10-22)
To be able to achieve their physics goals, future neutrino-oscillation experiments will need to reconstruct the neutrino energy with very high accuracy. In this work, we analyze how the energy reconstruction may be affected ...
