In this paper we develop a path-integral formulation of {ital classical} Hamiltonian dynamics, that means we give a functional-integral representation of {ital classical} transition probabilities.… Expand

We present a new technique for analyzing heavy-quark bound states in lattice QCD. The method is based upon a nonrelativistic reformulation of the heavy-quark dynamics that is systematically developed… Expand

A method for computing electromagnetic properties of hadrons in lattice QCD is described and preliminary numerical results are presented. The electromagnetic field is introduced dynamically, using a… Expand

The results of an extensive study of {ital B}-meson properties in quenched lattice QCD are presented. The studies are carried out in the static quark limit where the {ital b} quark is taken to be… Expand

In this paper we generalize previous work done on the path-integral approach to classical mechanics and its symmetries. We study in particular the case that the components of the symplectic two-form… Expand

We consider the effects of repulsive electron-electron interactions between electrons of like spin in conducting polymers. Because the ratio W/2m of the physical bandwidth W to the band gap 2m is… Expand

The scattering of Goldstone and longitudinal gauge bosons in weak-interaction theories with a strongly coupled Higgs sector is studied. By combining low-energy theorems with analyticity, unitarity,… Expand

A lattice Virasoro algebra is constructed for the Baxter eight-vertex model. The operator L/sub 0/ is obtained from the logarithm of the corner transfer matrix and is given by the first moment of the… Expand
