Interplay between inhomogeneous chiral and crystalline color-superconducting phases in the two-flavor NJL model
Chengfu Mu, Hosein Gholami, Michael Buballa
We study the interplay between the chiral density wave (CDW) and the single-plane-wave Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) phase of color-superconducting matter in two-flavor q…
Removing cutoff artifacts in the NJL model by a Renormalization Group consistent treatment
Hosein Gholami, Marco Hofmann, Michael Buballa
We summarize how a renormalization-group (RG)-consistent treatment removes well-known artifacts in NJL-model descriptions of color-superconducting quark matter. We introduce two RG…
Renormalizing the Quark-Meson-Diquark Model
Hosein Gholami, Lennart Kurth, Ugo Mire +2
We present a comprehensive study of the two-flavor Quark--Meson--Diquark (QMD) model by comparing a renormalization approach with a renormalization-group (RG) consistent mean-field…
Renormalization-group consistent treatment of color superconductivity in the NJL model
Hosein Gholami, Marco Hofmann, Michael Buballa
The Nambu-Jona-Lasinio (NJL) model and specifically its extension to color superconductivity (CSC) is a popular effective model for investigating dense quark matter. However, the r…
Astrophysical constraints on color-superconducting phases in compact stars within the RG-consistent NJL model
Hosein Gholami, Ishfaq Ahmad Rather, Marco Hofmann +2
We determine parameters of the renormalization group-consistent three-flavor color-superconducting Nambu-Jona-Lasinio (NJL) model that are suited to investigate possible compact-st…
