Charge assignments in multiple-U(1) gauge theories
(American Physical Society, 1999-12-01)
We discuss the choice of gauge field basis in multiple-U(1) gauge theories. We find that there is a preferred basis, specified by the charge orthogonality condition, in which the U(1) gauge fields do not mix under one-loop ...
Energies and residues of the nucleon resonances N(1535) and N(1650)
(American Physical Society, 1998-12)
We extract pole positions for the N(1535) and N(1650) resonances using two different models. The positions are determined from fits to different subsets of the existing pi N --> pi N, pi N --> eta N, and gamma p --> eta p ...
Exact results for the Kardar-Parisi-Zhang equation with spatially correlated noise
Photogeneration action spectroscopy of neutral and charged excitations in films of a ladder-type poly(para-phenylene)
(American Physical Society, 1999-04-19)
The photogeneration quantum efficiency action spectra of long-lived neutral and charged excitations in films of a ladder-type poly(para-phenylene) were measured. We found that both tripler and polaron action spectra show, ...

Critical dynamics at incommensurate phase transitions and NMR relaxation experiments

Infrared activity in the Aurivillius layered ferroelectric SrBi2Ta2O9
(American Physical Society, 1998-03-01)
Experimental studies were carried out on infrared-active phonons in the Aurivillius ferroelectric SrBi2Ta2O9 (SBT), using reflectivity measurements (down to 200 cm(-1)) and transmission measurements (down to 100 cm(-1)) ...
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). ...
Predictions of m(b)/m(tau) and m(t) in an asymptotically nonfree theory
