Holographic deconfinement transition in the presence of a magnetic field (1307.6498v4)
Published 24 Jul 2013 in hep-th and hep-ph
Abstract: We investigate the thermodynamics of the flavour sector of the Sakai-Sugimoto model in the presence of a magnetic field. Renormalizing the euclidean Dirac-Born-Infeld action in the antipodal limit, we find for the confined and deconfined phases positive contributions to the pressures that grow with the magnetic field. We also obtain positive magnetic susceptibilities indicating a paramagnetic behaviour of quarks. Using these results we estimate a \lambda2/N_c correction to the deconfinement temperature that decreases as a function of the magnetic field.
