Radiative corrections to the Casimir energy and effective field theory
Finn Ravndal, Jan B. Thomassen
We discuss radiative corrections to the Casimir effect from an effective field theory point of view. It is an improvement and more complete version of a previous discussion by Kong…
Chiral anomalies and Poincare invariance
Jan B. Thomassen
I study variations of the fermionic determinant for a nonabelian Dirac fermion with external vector and axial vector sources. I consider different regularizations, leading to diffe…
Bosonization in four dimensions: The smooth way
Jan B. Thomassen
I investigate bosonization in four dimensions, using the smooth bosonization scheme. I argue that generalized chiral ``phases'' of the fermion field corresponding to chiral phase r…
Chiral Poincare transformations and their anomalies
Jan B. Thomassen
I consider global transformations of a Dirac fermion field, that are generated by the generators of Poincar'e transformations, but with a γ_5 appended. Such chiral translations and…
Jacobians of chiral transformations and two-dimensional bosonization
Jan B. Thomassen
We formulate a complete path integral bosonization procedure for any fermionic theory in two dimensions. The method works equally well for massive and massless fermions, and is a g…
Two-Dimensional Bosonization from Variable Shifts in the Path Integral
Jan B. Thomassen
A method to perform bosonization of a fermionic theory in (1+1) dimensions in a path integral framework is developed. The method relies exclusively on the path integral property of…
