REMARKS ON THE DISPERSION-RELATIONS USED TO CALCULATE DELTA-RHO
(American Physical Soc, 1995-06-01)
We use the operator product expansion (OPE) to show that nonperturbative QCD corrections to Δρ can be calculated using unsubtracted dispersion relations for either the transverse or the longitudinal vacuum polarization ...
OBLIQUE CORRECTIONS TO THE W-WIDTH

Charge assignments in multiple-U(1) gauge theories
(American Physical Soc, 1999-12-01)
Dispersion of a single hole in the t-J model
(American Physical Society, 1997-03-01)
The dispersion of a single hole in the t-J model obtained by the exact result of 32 sites and the results obtained by self-consistent Born approximation and the Green function Monte Carlo method can be simply derived by a ...
Crossover From Self-Similar to Self-Affine Structures in Precolation
(Editions Physique, 1994-05-20)
We study the crossover from self-similar scaling behavior to asymptotically self-affine (anisotropic) structures. As an example, we consider bond percolation with one preferred direction. Our theory is based on a ...
Exact results for the Kardar-Parisi-Zhang equation with spatially correlated noise
Scaling regimes and critical dimensions in the Kardar-Parisi-Zhang problem
(E D P Sciences, 1999-07-01)
Critical dynamics at incommensurate phase transitions and NMR relaxation experiments
(Amer Physical Soc, 1999-05-01)
Photogeneration and recombination processes of neutral and charged excitations in films of a ladder-type poly(para-phenylene)
(American Physical Society, 1999-08-15)
We introduce a version of the cw photomodulation technique, measured far from the steady state, for obtaining the quantum efficiency, eta, of long-lived photoexcitations in pi-conjugated polymers. We apply this technique ...
