| 英文摘要 | Magnetic effects on chiral phase transition have been investigated in a modified soft-wall ads/qcd model, in which the dilaton field is taken to be negative at the ultraviolet region and positive at the infrared region as in phys. rev. d 93 (2016) 101901 and jhep 04 (2016) 036. the magnetic field is introduced into the background geometry by solving the einstein-maxwell system. after embedding the magnetized background geometry into the modified soft-wall model, the magnetic field dependent behavior of chiral condensate is worked out numerically. it is found that, in the chiral limit, the chiral phase transition remains as a second order at finite magnetic field b, while the symmetry restoration temperature and chiral condensate decrease with the increasing of magnetic field in small b region. when including finite quark mass effect, the phase transition turns to be a crossover one, and the transition temperature still decreases with increasing magnetic field b when b is not very large. in this sense, inverse magnetic catalysis effect is observed in this modified soft-wall ads/qcd model. |
