Second sound in Fermi gases at the BCS-BEC crossover
H. Heiselberg
The thermodynamic potential is calculated for a uniform superfluid gas of fermi atoms from the mean field BCS equations including corrections from induced interactions, Hartree-Foc…
Neutron Star Masses, Radii and Equation of State
Henning Heiselberg
A review of current neutron star masses and radius measurements is given and the resulting constraints on modern equation of states for nuclear matter. Phase transitions in particu…
Color Superconducting Quark Matter in Neutron Stars
H. Heiselberg
Color superconductivity in quark matter is studied for electrically charge neutral neutron star matter in -equilibrium. Both bulk quark matter and mixed phases of quark and nucl…
Phases of Dense Matter in Neutron Stars
H. Heiselberg
After a brief history of neutron stars and supernovae recent developments are discussed. Based on modern nucleon-nucleon potentials more reliable equations of state for dense nucle…
Electrical Conduction in the Early Universe
H. Heiselberg
The electrical conductivity has been calculated in the early universe at temperatures below as well as above the electroweak vacuum scale, GeV. Debye and dynamical s…
Signatures of QCD Matter at RHIC
Henning Heiselberg, Andrew D. Jackson
We discuss possible experimental signatures of forming a Quark-Gluon plasma in high energy nuclear collisions. In first order phase transitions such as the chiral symmetry restorat…
