Phase diagram of QCD in a magnetic field: A review
Jens O. Andersen, William R. Naylor, Anders Tranberg
We review in detail recent advances in our understanding of the phase structure and the phase transitions of hadronic matter in strong magnetic fields and zero quark chemical p…
Equation of State for QCD at finite temperature and density. Resummation versus lattice data
Jens O. Andersen, Najmul Haque, Munshi G. Mustafa +2
The perturbative series for finite-temperature field theories has very poor convergence properties and one needs a way to reorganize it. In this talk, I review two ways of reorgani…
Inverse magnetic catalysis and regularization in the quark-meson model
Jens O. Andersen, William R. Naylor, Anders Tranberg
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…
Three loop HTL perturbation theory at finite temperature and chemical potential
Michael Strickland, Jens O. Andersen, Aritra Bandyopadhyay +3
In this proceedings contribution we present a recent three-loop hard-thermal-loop perturbation theory (HTLpt) calculation of the thermodynamic potential for a finite temperature an…
Effective Lagrangians for quantum many-body systems
Jens O. Andersen, Tomas Brauner, Christoph P. Hofmann +1
The low-energy and low-momentum dynamics of systems with a spontaneously broken continuous symmetry is dominated by the ensuing Nambu-Goldstone bosons. It can be conveniently encod…
Three-loop HTLpt thermodynamics at finite temperature and chemical potential
Najmul Haque, Aritra Bandyopadhyay, Jens O. Andersen +3
We calculate the three-loop thermodynamic potential of QCD at finite temperature and chemical potential(s) using the hard-thermal-loop perturbation theory (HTLpt) reorganization of…
