Goldstone boson currents in a kaon condensed CFL phase
Andreas Gerhold, Thomas Schaefer, Andrei Kryjevski
We study the stability of the kaon condensed color-flavor locked (CFL) phase of dense quark matter with regard to the formation of a non-zero Goldstone boson current. In the kaon c…
Chromomagnetic stability of the CFL phase with a meson current
Andreas Gerhold
We show that the color-flavor locked (CFL) phase of dense quark matter is unstable with respect to the formation of a Goldstone boson current in the vicinity of the point $m_s^2=2μ…
Meson current in the CFL phase
A. Gerhold, T. Schäfer
We study the stability of the color-flavor locked (CFL) phase of dense quark matter with regard to the formation of a non-zero Goldstone boson current. We show that an instability…
Thermodynamics of QCD at large quark chemical potential
Andreas Gerhold, Andreas Ipp, Anton Rebhan
We review the existing weak-coupling results on the thermodynamic potential of deconfined QCD at small and large quark chemical potential and compare with results from lattice gaug…
Aspects of cold dense quark matter
Andreas Gerhold
This thesis is devoted to properties of quark matter at high density and (comparatively) low temperature, which might exist in the interior of compact stars. The specific heat and…
Fermionic dispersion relations in ultradegenerate relativistic plasmas beyond leading logarithmic order
A. Gerhold, A. Rebhan
We determine the dispersion relations of fermionic quasiparticles in ultradegenerate plasmas by a complete evaluation of the on-shell hard-dense-loop-resummed one-loop fermion self…
