磁场中手征跃迁的新Lifshitz点
Novel Lifshitz point for chiral transition in the magnetic field
摘要：
基于广义Ginzburg-Landau理论，讨论了在磁场存在下的手征相变。在考虑手征密度波的情况下，我们证明了对于非零夸克数的化学势，手征反常会导致非均匀手征相。在消失的化学势线上出现了新的Lifshitz点，这可以通过格点量子色动力学模拟直接得到。
英文摘要：
Based on the generalized Ginzburg-Landau theory, chiral phase transition is discussed in the presence of magnetic field. Considering the chiral density wave we show chiral anomaly gives rise to an inhomogeneous chiral phase for nonzero quark-number chemical potential. Novel Lifshitz point appears on the vanishing chemical potential line, which may be directly explored by the lattice QCD simulation.
