Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
Andersen, Jens O.; Naylor, William R.; Tranberg, Anders (Journal article; Peer reviewed, 2014-04)We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magnetic background B at finite temperature T ... -
Inverse magnetic catalysis and regularization in the quark-meson model
Andersen, Jens O.; Naylor, William R.; Tranberg, Anders (Journal article; Peer reviewed, 2015-02)Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral ...
