Coronal bright point statistics II. Magnetic polarities and mini loops
I. Kraus, Ph. -A. Bourdin, J. Zender +2
Context. The solar corona maintains temperatures of a million Kelvin or more. The plasma heating mechanisms responsible for these extreme temperatures are still unclear. Large regi…
Stringy phenomenology with preon models
Risto Raitio
We compare, following Pati, global symmetries our topological supersymmetric preon model with the heterotic E_8 x E_8 string theory. We include Pati's supergravity based preon mode…
A Chern-Simons model for baryon asymmetry
Risto Raitio
In search of a phenomenological model that would describe physics from Big Bang to the Standard Model (SM), we propose a model with the following properties (i) above an energy abo…
A Stringy Model of Pointlike Particles
Risto Raitio
A previous supersymmetric preon scenario for visible matter particles is extended to the dark sector. In addition, the scenario is reformulated as a Double Field Theory (DFT) with…
Magnetism of quantum dot clusters: A Hubbard model study
J. -P. Nikkarila, M. Koskinen, M. Manninen
Magnetic properties of two and three-dimensional clusters of quantum dots are studied with exact diagonalization of a generalized Hubbard model. We study the weak coupling limit, w…
