Core-corona decomposition of compact (neutron) stars compared to NICER data including XTE J1814-338

Rico Zöllner, Burkhard Kämpfer

A core-corona decomposition of compact (neutron) star models is compared to recent NICER data of masses and radii. It is in particular interesting to capture the outlier XTE~J1814-…

Exotic Cores with and without Dark-Matter Admixtures in Compact Stars

Rico Zöllner, Burkhard Kämpfer

We parameterize the core of compact spherical star configurations by a mass () and a radius () and study the resulting admissible areas in the total-mass vs. total-radius…

Holographic bottomonium formation in a cooling strong-interaction medium at finite baryon density

Rico Zöllner, Burkhard Kämpfer

The shrinking of the bottomonium spectral function towards narrow quasi-particle states in a cooling strong-interaction medium at finite baryon density is followed within a hologra…

Phase structures emerging from holography with Einstein gravity -- dilaton models at finite temperature

Rico Zöllner, Burkhard Kampfer

Asymptotic AdS Riemann space-times in five dimensions with a black brane (horizon) sourced by a fully back-reacted scalar field (dilaton) offer -- via the holographic dictionary --…

Holography at QCD-

Rico Zöllner, Burkhard Kampfer

Within an extended soft wall model, we study the temperature dependence of the lowest vector meson states. Scales are adjusted by using as input the meson mass in vacuum and th…

Holographically emulating sequential versus instantaneous disappearance of vector mesons in a hot environment

Rico Zöllner, Burkhard Kampfer

Descent extensions of the soft-wall model are used to accommodate two variants of Regge trajectories of vector meson excitations. At non-zero temperatures, various options for eith…
