Chiral anomaly induces superconducting baryon crystal
Geraint W. Evans, Andreas Schmitt
It was previously shown within chiral perturbation theory that the ground state of QCD in a sufficiently large magnetic field and at nonvanishing, but not too large, baryon chemica…
Critical magnetic fields in a superconductor coupled to a superfluid
Alexander Haber, Andreas Schmitt
We study a superconductor that is coupled to a superfluid via density and derivative couplings. Starting from a Lagrangian for two complex scalar fields, we derive a temperature-de…
Holographic baryonic matter in a background magnetic field
Florian Preis, Anton Rebhan, Andreas Schmitt
We discuss the effect of baryonic matter on the zero-temperature chiral phase transition at finite chemical potential in the presence of a background magnetic field. The main part…
Inverse magnetic catalysis in dense holographic matter
Florian Preis, Anton Rebhan, Andreas Schmitt
We study the chiral phase transition in a magnetic field at finite temperature and chemical potential within the Sakai-Sugimoto model, a holographic top-down approach to (large-N_c…
Holographic chiral currents in a magnetic field
Anton Rebhan, Andreas Schmitt, Stefan Stricker
In the presence of a quark chemical potential, a magnetic field induces an axial current in the direction of the magnetic field. We compute this current in the Sakai-Sugimoto model…
Anomalies and the chiral magnetic effect in the Sakai-Sugimoto model
Anton Rebhan, Andreas Schmitt, Stefan A. Stricker
In the chiral magnetic effect an imbalance in the number of left- and right-handed quarks gives rise to an electromagnetic current parallel to the magnetic field produced in noncen…
