具有同位旋化学势的全息QCD

Holographic QCD with Isospin Chemical Potential

Andrei Parnachev

摘要:

我们考虑了D4-D8- \bar D8膜的组态,它对应于重子数和同位旋的非零温度和化学势的大N QCD。我们研究了这个模型的全息对偶,发现了一个丰富的相结构。相,区分夸克凝聚的值,分离的表面的一级相变。这幅图在许多方面与手征极限下QCD的预期相结构相似。

英文摘要:

We consider configurations of D4-D8-\bar D8 branes which correspond to large N QCD with non-vanishing temperature and chemical potential for baryon number and isospin. We study the holographic dual of this model and find a rich phase structure. The phases, distinguished by the values of quark condensates, are separated by the surfaces of first order phase transitions. The picture is in many respects similar to the expected phase structure of QCD in the chiral limit.
