Classical Worldsheets for String Scattering on Flat and AdS Spacetime
Charles M. Sommerfield, Charles B. Thorn
We present a study of the worldsheets that describe the classical limit of various string scattering processes. Our main focus is on string scattering in AdS spacetime because of i…

Aharonov-Bohm and Coulomb Scattering Near the Forward Direction
Charles M. Sommerfield, Hisakazu Minakata
The exact wave functions that describe scattering of a charged particle by a confined magnetic field (Aharonov-Bohm effect) and by a Coulomb field are analyzed. It is well known th…

On Abelian Bosonization of Free Fermi Fields in Three Space Dimensions
Ramesh Abhiraman, Charles M. Sommerfield
One of the methods used to extend two-dimensional bosonization to four space-time dimensions involves a transformation to new spatial variables so that only one of them appears kin…
