The Covariant Picard Groupoid in Differential Geometry
Stefan Waldmann
In this article we discuss some general results on the covariant Picard groupoid in the context of differential geometry and interpret the problem of lifting Lie algebra actions to…
Einstein's impact on the physics of the twentieth century
Domenico Giulini, Norbert Straumann
Starting with Einstein's famous papers of 1905, we review some of the ensuing developments and their impact on present-day physics. We attempt to cover topics that are of interest…
State space structure and entanglement of rotationally invariant spin systems
Heinz-Peter Breuer
We investigate the structure of SO(3)-invariant quantum systems which are composed of two particles with spins j_1 and j_2. The states of the composite spin system are represented…
Fractional charge in the noise of Luttinger liquid systems
B. Trauzettel, I. Safi, F. Dolcini +1
The current noise of a voltage biased interacting quantum wire adiabatically connected to metallic leads is computed in presence of an impurity in the wire. We find that in the wea…
On the visibility of electron-electron interaction effects in field emission spectra
T. L. Schmidt, A. Komnik
One of the most convenient methods to obtain information about the energy distribution function of electrons in conducting materials is the measurement of the energy resolved curre…
Phase synchronization from noisy univariate signals
A. G. Rossberg, K. Bartholome, H. U. Voss +1
We present methods for detecting phase synchronization of two unidirectionally coupled, self-sustained noisy oscillators from a signal of the driven oscillator alone. One method de…
