Constraints on top-color assisted technicolor models from vertex corrections
(American Physical Soc, 1999-07-01)
Systematic scaling in the low-energy excitations of the t-J model in one and two dimensions
(American Physical Society, 1997-05-01)
We present an exact diagonalization study of the low-energy singlet and triplet states for both the one-dimensional (1D) and 2D t-J models. A scan of the parameter ratio J/t shows that for most low-energy states in both ...
Computational simulation of type-II superconductivity including pinning phenomena
(American Physical Society, 1995-06-15)
A flexible tool, based on the finite-element method, for the computational simulation of vortex phenomena in type-II superconductors has been developed. These simulations use refined or newly developed phenomenological ...
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 ...
Critical dynamics at incommensurate phase transitions and NMR relaxation experiments
(Amer Physical Soc, 1999-05-01)
Pole versus Breit-Wigner resonance description of the orbitally excited baryons
(American Physical Society, 1999-06)
We consider the masses used in recent studies involving the nonstrange sector of the l = 1 baryons. The use of T-matrix and K-matrix poles versus the conventional Breit-Wigner masses is discussed within the context of a ...
Origin of scintillation in cerium_doped oxide crystals
(AIP Publishing, 1995-05)
We propose here a model of the scintillation from complex oxide single crystalsdoped with Ce3+ ions to explain the correlation observed between scintillation light yield and intrinsic luminescence of the matrix.
Charge assignments in multiple-U(1) gauge theories
(American Physical Soc, 1999-12-01)
Monte Carlo simulation calculation of the critical coupling constant for two-dimensional continuum phi(4) theory
(American Physical Society, 1998-10)
We perform a Monte Carlo simulation calculation of the critical coupling constant for the continuum two-dimensional (lambda/4) phi(4) theory. The critical coupling constant we obtain is [lambda/mu(2)](crit) = 10.26(-.04)(+.08). ...
