Saturation of the R-mode Instability
Phil Arras, Eanna E. Flanagan, Sharon M. Morsink +3
Rossby waves (r-modes) in rapidly rotating neutron stars are unstable because of the emission of gravitational radiation. We study saturation of this instability by nonlinear trans…
Nonlinear mode coupling in rotating stars and the r-mode instability in neutron stars
A. Katrin Schenk, Phil Arras, Eanna E. Flanagan +2
We develop the formalism required to study the nonlinear interaction of modes in rotating Newtonian stars in the weakly nonlinear regime. The formalism simplifies and extends previ…
The electroweak chiral Lagrangian reanalyzed
Andreas Nyffeler, Andreas Schenk
In this paper we reanalyze the electroweak chiral Lagrangian with particular focus on two issues related to gauge invariance. Our analysis is based on a manifestly gauge-invariant…
Gauge-invariant Green's functions for the bosonic sector of the standard model
Andreas Nyffeler, Andreas Schenk
There are many applications in gauge theories where the usually employed framework involving gauge-dependent Green's functions leads to considerable problems. In order to overcome…
Hot, Rotating Disks In General Relativity: Collisionless Equilibrium Models
A. Katrin Schenk, Stuart L. Shapiro, Saul A. Teukolsky
We present a method for constructing equilibrium disks with net angular momentum in general relativity. The method solves the relativistic Vlasov equation coupled to Einstein's equ…
A Manifestly Gauge-Invariant Approach to Charged Particles
A. Schenk
In this article we provide a manifestly gauge-invariant approach to charged particles. It involves (1) Green functions of gauge-invariant operators and (2) Feynman rules which do n…
