On the Dark-Energy Enigma
Ali H. Chamseddine, Jürg Fröhlich
We present a model that offers an explanation for the presence of (Dark Matter and) Dark Energy in the universe. A key idea is to express the volume form of the Lorentzian metric o…
Cosmological Magnetic Fields from Ultralight Dark Matter
Robert Brandenberger, Jürg Fröhlich, Hao Jiao
We propose a mechanism for the generation of magnetic fields on cosmological scales that is operative after recombination. An essential ingredient is an instability (of parametric…
New Scalar Field Quartessence
Robert Brandenberger, Rodrigo R. Cuzinatto, Jürg Fröhlich +1
We propose a cosmological scenario involving a scalar field, , that is a source of Dark Matter as well as of Dark Energy. Besides , the Lagrangian of the field theory envisag…
The turbulent chiral-magnetic cascade in the early universe
Axel Brandenburg, Jennifer Schober, Igor Rogachevskii +5
The presence of asymmetry between fermions of opposite handedness in plasmas of relativistic particles can lead to exponential growth of a helical magnetic field via a small-scale…
New applications of the chiral anomaly
J. Fröhlich, B. Pedrini
We describe consequences of the chiral anomaly in the theory of quantum wires, the (quantum) Hall effect, and of a four-dimensional cousin of the Hall effect. We explain which aspe…
