The importance of inter-site coherences in the x-ray absorption spectra of mixed-valent systems
inter-site coherences in the x-ray mixed-valent systems
2010/11/19
We study the importance of inter-site coherences and quantum interference effects in
the x-ray absorption spectroscopy (XAS) of mixed-valent systems. We demonstrate its importance,
first for a simpl...

The Importance of Strange Mesons in Neutron Star Properties
Strange Mesons Neutron Star Properties
2010/10/15
In order to obtain the properties of compact stellar objects, appropriate equations of state have to be used. In the literature, strange meson fields, namely the scalar meson field s¤(975) and the vec...
