'Stealth' singularities from self-gravitating fermions
Peter E. D. Leith, Chris A. Hooley, Keith Horne +1
We present a new analytic solution to the Einstein-Dirac equations formulated by Finster, Smoller, and Yau [Phys. Rev. D 59, 104020 (1999)] to describe the stationary states of a p…
The onset of filamentation on vorticity interfaces in two-dimensional Euler flows
David Dritschel, Adrian Constantin, Pierre Germain
Two-dimensional Euler flows, in the plane or on simple surfaces, possess a material invariant, namely the scalar vorticity normal to the surface. Consequently, flows with piecewise…
On the onset of filamentation on two-dimensional vorticity interfaces
Adrian Constantin, David Dritschel, Pierre Germain
We study an asymptotic nonlinear model for filamention on two-dimensional vorticity interfaces. Different re-formulations of the model equation reveal its underlying structural pro…
Gravitationally localized states of two neutral fermions interacting with a Higgs field
Peter E. D. Leith, Alasdair Dorkenoo Leggat, Chris A. Hooley +2
We present localized 'particle-like' states composed of a pair of neutral fermions interacting with a scalar Higgs field and the metric of spacetime, extending the Einstein-Dirac f…
Nonlinear effects in the excited states of many-fermion Einstein-Dirac solitons
Peter E. D. Leith, Chris A. Hooley, Keith Horne +1
We present an analysis of excited-state solutions for a gravitationally localized system consisting of a filled shell of high-angular-momentum fermions, using the Einstein-Dirac fo…
Fermion self-trapping in the optical geometry of Einstein-Dirac solitons
Peter E. D. Leith, Chris A. Hooley, Keith Horne +1
We analyze gravitationally localized states of multiple fermions with high angular momenta, in the formalism introduced by Finster, Smoller, and Yau [Phys Rev. D 59, 104020 (1999)]…
