Reconstructing the evolution of dark energy with variations of fundamental parameters
N. J. Nunes, T. Dent, C. J. A. P. Martins +1
Under the assumption that the variations of parameters of nature and the current acceleration of the universe are related and governed by the evolution of a single scalar field, we…
Perturbations in electromagnetic dark energy
Jose Beltran Jimenez, Tomi S. Koivisto, Antonio L. Maroto +1
It has been recently proposed that the presence of a temporal electromagnetic field on cosmological scales could explain the phase of accelerated expansion that the universe is cur…
Anderson localization of a weakly interacting one dimensional Bose gas
T. Paul, M. Albert, P. Schlagheck +2
We consider the phase coherent transport of a quasi one-dimensional beam of Bose-Einstein condensed particles through a disordered potential of length L. Among the possible differe…
Conformational properties of compact polymers
Manfred Bohn, Dieter W. Heermann
Monte Carlo simulations of coarse-grained polymers provide a useful tool to deepen the understanding of conformational and statistical properties of polymers both in physical as we…
Nonperturbative and perturbative aspects of photo- and electroproduction of vector mesons
H. G. Dosch, Erasmo Ferreira
We discuss various aspects of vector meson production, first analysing the interplay between perturbative and nonperturbative aspects of the QCD calculation. Using a general method…
Inflation from N-Forms and its stability
Tomi S. Koivisto, David F. Mota, Cyril Pitrou
Anisotropic and isotropic slow-roll inflation supported by n-forms are sought. Canonical field strengths and their duals are taken into account, and they are allowed to have a pote…
