Ground state energy of an interacting electron system in the background of two opposite magnetic strings
J. Dietel
Motivated by our earlier work, we show in this paper rigorously that the ground state energy and degeneracy of an infinitely extended system of interacting electrons in the backgro…

Applications of Chern-Simons Ward Identities to log(Tτ) Conductivity Calculations of the nu=1/2 System
Juergen Dietel
We reconsider the theory of the half-filled Landau level with impurities using the Chern-Simons formulation and study Ward identities for the Chern-Simons theory. From these we get…
