QCD三味Larkin-Ovchinnikov-Fulde-Ferrel相的研究进展
Recent advances in the three flavor Larkin-Ovchinnikov-Fulde-Ferrel phase of QCD
摘要：
本文综述了QCD三味Larkin-Ovchinnikov-Fulde-Ferrell（LOFF）相的研究进展。在最简单的单平面波结构中，利用NJL四费米子耦合，我们利用自由能的Ginzburg-Landau展开，探索了具有三种风味的LOFF相。我们已经发现，这个阶段不遭受色磁不稳定性的问题。初步研究了夸克物质在上述阶段的天体物理效应，并自洽地估算了将配对效应扩展到CubeX和2Cube 45 z结构的奇异夸克质量。最后，我们研究了Goldstone玻色子在LOFF相有利立方结构中凝聚的可能性。
英文摘要：
We present a summary of the recent advances achieved in the study of three flavor Larkin-Ovchinnikov-Fulde-Ferrell (LOFF)phase of QCD. We have explored, using a Ginzburg-Landau expansion of the free energy, the LOFF phase with three flavors, in the simplest single plane wave structure, using the NJL four-fermion coupling. We have found that this phase does not suffer the chromo-magnetic instability problem. A preliminary study of astrophysical effects of quark matter in the aforementioned phase has been done and we have evaluated self-consistently the strange quark mass extending the pairing ansatz to the CubeX and 2Cube45z structure. Finally we have investigated the possibility of Goldstone bosons condensation in the favored cubic structures of LOFF phase.
