Two-Fluid Schwarzschild Solution
Rico Zöllner, Burkhard Kämpfer
We consider the interior two-fluid Schwarzschild solution. That is a model of compact (neutron) stars with admixed dark matter. The two constant energy densities generalize the int…
Towards a warm holographic equation of state by an Einstein-Maxwell-dilaton model
Rico Zöllner, Burkhard Kämpfer
The holographic Einstein-Maxwell-dilaton model is employed to map state-of-the-art lattice QCD thermodynamics data from the temperature () axis towards the baryon-chemical poten…
Masses of compact (neutron) stars with distinguished cores
Rico Zollner, Minghui Ding, Burkhard Kampfer
The impact of the core mass on the compact/neutron-star mass-radius relation is studied. Besides the mass, the core is parameterized by its radius and surface pressure, which suppo…
Holographic vector mesons in a dilaton background
Rico Zöllner, Burkhard Kämpfer
Within a holographic framework, we consider vector mesons riding on a gravity-dilaton background. The latter one is determined directly from a Schrödinger equivalent potential whic…
Extended soft-wall model for the QCD phase diagram
Rico Zöllner, Falk Wunderlich, Burkhard Kampfer
The soft-wall model, emerging as bottom-up holographic scenario anchored in the AdS/CFT correspondence, displays the disappearance of normalisable modes referring to vector mesons…
