Color superconducting quark matter in compact stars
D. B. Blaschke, T. Klahn, F. Sandin
Recent indications for high neutron star masses (M \sim 2 M_sun) and large radii (R > 12 km) could rule out soft equations of state and have provoked a debate whether the occurence…
Mass limits for heavy neutrinos
Erik Elfgren, Sverker Fredriksson
Neutrinos heavier than GeV are not excluded by particle physics data. Stable neutrinos heavier than this might contribute to the cosmic gamma ray background through…
Equation of state at high densities and modern compact star observations
D. Blaschke, T. Klahn, F. Sandin
Recently, observations of compact stars have provided new data of high accuracy which put strong constraints on the high-density behaviour of the equation of state of strongly inte…
Dust Distribution during Reionization
Erik Elfgren, Francois-Xavier Désert, Bruno Guiderdoni
The dust produced by the first generation of stars will be a foreground to cosmic microwave background. In order to evaluate the effect of this early dust, we calculate the power s…
The effect of dipole-dipole interactions between atoms in an active medium
V. V. Berezovsky, L. I. Men'shikov, S. Oberg +1
Based on the results of numerical modeling, it is shown that dipole-dipole interactions among atoms in the active medium influences strongly the character of the associated superra…
Thermodynamics of a Heavy Ion-Irradiated Superconductor: the Zero-Field Transition
C. J. van der Beek, Thierry Klein, René Brusetti +4
Specific heat measurements show that the introduction of amorphous columnar defects considerably affects the transition from the normal to the superconducting state in zero magneti…
