Cutoff dependence and Lorentz invariance of the Casimir effect
C. R. Hagen
The Casimir force between two conducting planes is considered in both the electromagnetic and scalar field cases. This is done by the usual summation over energy eigenmodes of the…
Reply to comment on Casimir energy for spherical boundaries
C. R. Hagen
It is shown that the recent criticism of Brevik et al. (hep-th/0004041) is in error.
Non-thermalizability of a Quantum Field Theory
C. R. Hagen
The problem of understanding the role of large gauge transformations in thermal field theories has recently inspired a number of studies of a one dimensional field theory. Such wor…
Comment on "Equivalence of Several Chern-Simons Matter Models
C. R. Hagen
It is shown that a recent claim of equivalence between three Chern-Simons theories is not tenable.
Symmetry Under is Forbidden by Helicity Conservation
C. R. Hagen
The question as to whether helicity conservation in spin one-half Aharonov Bohm scattering is sufficient in itself to determine uniquely the form of the spinor wave function near t…
Comment on Internal Frame Dragging and a Global Analog of the Aharonov-Bohm Effect
C. R. Hagen
It is shown that AB-like cross sections can be obtained from symmetry breaking which does not require infinite energy, angular dependence in the symmetry breaking term, or a nontri…
