Propagating and annihilating vortex dipoles in the Gross-Pitaevskii equation

Cecilia Rorai, K. R. Sreenivasan, Michael E. Fisher

Quantum vortex dynamics in Bose-Einstein condensates or superfluid helium can be informatively described by the Gross-Pitaevskii (GP) equation. Various approximate analytical formu…

Non-Renormalization and Naturalness in a Class of Scalar-Tensor Theories

Claudia de Rham, Gregory Gabadadze, Lavinia Heisenberg +1

We study the renormalization of some dimension-4, 7 and 10 operators in a class of nonlinear scalar-tensor theories. These theories are invariant under: (a) linear diffeomorphisms…

FLUXCAP: A flux-coupled ac/dc magnetizing device

Daniel B. Gopman, Huanlong Liu, Andrew D. Kent

We report on an instrument for applying ac and dc magnetic fields by capturing the flux from a rotating permanent magnet and projecting it between two adjustable pole pieces. This…
