Negative Energy Densities in Quantum Field Theory With a Background Potential
Noah Graham, Ken D. Olum
We present a general procedure for calculating one-loop ``Casimir'' energy densities for a scalar field coupled to a fixed potential in renormalized quantum field theory. We implem…

Quaternionic Madelung Transformation and Non-Abelian Fluid Dynamics
Peter J. Love, Bruce M. Boghosian
In the 1920's, Madelung noticed that if the complex Schroedinger wavefunction is expressed in polar form, then its modulus squared and the gradient of its phase may be interpreted…

Solitonic D-branes and brane annihilation
Gia Dvali, Alexander Vilenkin
We point out some intriguing analogies between field theoretic solitons (topological defects) and D-branes. Annihilating soliton-antisoliton pairs can produce stable solitons of lo…
