Spectral Properties and Lifetimes of Neutral Spin-1/2-Fermions in a Magnetic Guide
Igor Lesanovsky, Peter Schmelcher
We investigate the resonant motion of neutral spin-1/2-fermions in a magnetic guide. A wealth of unitary and anti-unitary symmetries is revealed in particular giving rise to a two-…
Large scale inhomogeneity and local dynamical friction
A. Just, J. Penarrubia
We investigate the effect of a density gradient on Chandrasekhar's dynamical friction formula based on the method of 2-body encounters in the local approximation. We apply these ge…
Discovery of magnetic fields in hot subdwarfs
S. J. O'Toole, S. Jordan, S. Friedrich +1
We present initial results of a project to measure mean longitudinal magnetic fields in a group of sdB/OB/O stars. The project was inspired by the discovery of three super-metal-ri…
Cosmological bounds on the equation of state of dark matter
Christian M. Mueller
In this exploratory study, we investigate the bounds on the equation of state of dark matter. Modeling dark matter as a fluid component, we take into account both positive and nega…
B-Meson Properties from Modified Sum Rule Analyses
Tobias Kleinschmidt
We introduce two approaches to analyses of Borel sum rules. In the first method, we take the Borel mass M2 to infinity. Here, the sum rules become very sensitive to the chosen thre…
Rydberg Atoms in a Magnetic Guide
Igor Lesanovsky, Joerg Schmiedmayer, Peter Schmelcher
We investigate electronically excited atoms in a magnetic guide. It turns out that the Hamiltonian describing this system possesses a wealth of both unitary as well as antiunitary…
