Effects of Strong Magnetic Fields on the Hadron-Quark Deconfinement Transition

Abstract

The aim of the present work is to investigate the effects of strong magnetic fields on the hadronquark phase transition point at zero temperature. To describe the hadronic phase, a relativistic mean field (RMF) model is used and to describe the quark phase a density dependent quark mass model (DDQM) is employed. As compared with the results obtained with non-magnetised matter, we observe a shift of the transition point towards higher pressures and, generally also towards higher chemical potentials. An investigation of the phase transitions that could sustain hybrid stars is also performed.

“…As can be seen from the figure, a strong magnetic field pushes the onset of quark matter to higher densities and pressures, thus further delaying the appearance of a potential quark core in neutron stars. In other studies, it is found in a similar way that a strong magnetic field shifts the transition to quark matter to higher densities, see the review [51], too.…”
