Performance of quantum phase gates with cold trapped atoms
A. Negretti, T. Calarco, M. A. Cirone +1
We examine the performance of a quantum phase gate implemented with cold neutral atoms in microtraps, when anharmonic traps are employed and the effects of finite temperature are a…
Massive scalar fields in the early Universe
Uwe Guenther, Alexander Zhuk
We discuss the role of gravitational excitons/radions in different cosmological scenarios. Gravitational excitons are massive moduli fields which describe conformal excitations of…
An asymptotic maximum principle for essentially linear evolution models
E. Baake, M. Baake, A. Bovier +1
Recent work on mutation-selection models has revealed that, under specific assumptions on the fitness function and the mutation rates, asymptotic estimates for the leading eigenval…
Duality of compact groups and Hilbert C*-systems for C*-algebras with a nontrivial center
Hellmut Baumgärtel, Fernando Lledó
In the present paper we prove a duality theory for compact groups in the case when the C*-algebra A, the fixed point algebra of the corresponding Hilbert C*-system (F,G), has a non…
The PLANET microlensing campaign: Implications for planets around galactic disk and bulge stars
M. Dominik, M. D. Albrow, J. -P. Beaulieu +17
With round-the-clock monitoring of galactic bulge microlensing events, the PLANET experiment constrains the abundance and can yield the discovery of planets down to the mass of ear…
Multistability, noise and attractor-hopping: The crucial role of chaotic saddles
Suso Kraut, Ulrike Feudel
We investigate the hopping dynamics between different attractors in a multistable system under the influence of noise. Using symbolic dynamics we find a sudden increase of dynamica…
