Unnatural Acts: Unphysical Consequences of Imposing Boundary Conditions on Quantum Fields
R. L. Jaffe
I examine the effect of trying to impose a Dirichlet boundary condition on a scalar field by coupling it to a static background. The zero point -- or Casimir -- energy of the field…

Heavy Fermion Quantum Effects in SU(2)_L Gauge Theory
E. Farhi, N. Graham, R. L. Jaffe +2
We explore the effects of a heavy fermion doublet in a simplified version of the standard electroweak theory. We integrate out the doublet and compute the exact effective energy fu…
