Deconfinement Phase Transition with External Magnetic Field in Friedberg-Lee Model
arXiv:1509.05151 · doi:10.1088/0256-307X/33/11/112501
Abstract
The deconfinement phase transition with external magnetic field is investigated in the Friedberg-Lee model. In the frame of functional renormalization group, we extend the often used potential expansion method for continuous phase transitions to the first-order phase transition in the model. By solving the flow equations we find that, the magnetic field displays a catalysis effect and it becomes more difficult to break through the confinement in hot and dense medium.
