報告題目： Quark mass gap in strong magnetic fields 報告人：蘇楠（Bielefeld University,德國）報告時間： 2014-6-30 15:00 報告地點：理科樓B315 摘要： The fact that magnetic fields enhance the chiral symmetry breaking has been known as magnetic catalysis. Recent lattice studies indicate that the QCD transition temperature decreases for increasing magnetic fields, which is however not in line with expectations from magnetic catalysis. In this talk, I will discuss the role of dynamical gluons in the study of the quark mass gap, emphasizing the characteristics of QCD from QED and effective models (such as the NJL type). The linear rising behavior of the chiral condensate at large magnetic fields, which has been observed on the lattice, is emerged when non-perturbative gluons are considered. The result is utilized to interpret the reduction of the transition temperature at large magnetic fields.
