磁场感应临界终点

Magnetic-Field Induced Critical Endpoint

Stefan Rechenberger

摘要:

利用Nambu-Jona-Lasinio模型分析了强相互作用物质的相图。特别强调的是它的依赖于外部磁场和同位旋化学势。利用瞬子效应引起的味混合,比较了磁场和同位旋化学势对同位旋破缺的影响。发现在低温和大的夸克化学势下,磁场根据其强度,诱导出一个新的临界端点或三相点。

英文摘要:

The phase diagram of strong interaction matter is analyzed utilizing the Nambu--Jona-Lasinio model. Special emphasis is placed on its dependence on an external magnetic field and isospin chemical potential. Using flavor mixing induced by instanton effects the influence of isospin breaking due to the magnetic field and the isospin chemical potential is compared. It is found that at low temperatures and large quark chemical potential the magnetic field, depending on its strength, induces a new critical endpoint or a triple point.
