Massive hybrid stars within the extended three-flavor quark-meson diquark model
Jens O. Andersen, Manuel Linares, Mathias P. Nødtvedt
We discuss the properties of the extended three-flavor quark-meson diquark (EQMD) model as a renormalizable low-energy effective model for QCD. The effective degrees of freedom are…
Quark-meson diquark model and color superconductivity in dense quark matter
Jens O. Andersen, Mathias P. Nødtvedt
We consider the two- and three-flavor QMD models as renormalizable low-energy models for QCD at finite quark chemical potentials with quarks, mesons, and diquarks as effective degr…
The effects of quantum instantons on the thermodynamics of the CP^(N-1) model
Jens O. Andersen, Daniel Boer, Harmen J. Warringa
Using the 1/N expansion, we study the influence of quantum instantons on the thermodynamics of the CP^(N-1) model in 1+1 dimensions. We do this by calculating the pressure to next-…
Ground State Pressure and Energy Density of a Homogeneous Bose Gas in Two Dimensions
Jens O. Andersen
We consider an interacting homogeneous Bose gas at zero temperature in two spatial dimensions. The properties of the system can be calculated as an expansion in powers of g, where…
Magnetization in 2+1 dimensional QED at Finite Temperature and Density
Jens O. Andersen, Tor Haugset
We consider Dirac fermions moving in a plane with a static homogeneous magnetic field orthogonal to the plane. We calculate the effective action at finite temperature and density.…
