在ABJM中嵌入大量风味

Embedding massive flavor in ABJM

Gabi Zafrir

摘要:

我们通过在RP 3上添加渐近包裹的D 6-膜,将大量基本物质添加到ABJM模型中。我们发现两种类型的解决方案在有限的温度,一个进入黑洞和一个结束之前的黑洞。我们分析了自由能随温度变化的行为,发现该体系在两种溶液之间存在相变,类似于D3-D 7体系。我们还分析了模型中的介子谱,发现了几个大质量的标量模,同样,很像D3-D 7系统。最后计算了两相的电导率。

英文摘要:

We add massive fundamental matter to the ABJM model by adding D6-branes wrapped asymptotically over RP3. We find two types of solutions at finite temperature, one that enters the black hole and one that ends before the black hole. We analyze the behavior of the free energy as a function of temperature, and find that the system exhibits a phase transition between the two types of solutions, similar to what happens in the D3-D7 system. We also analyze the meson spectrum in the model and find several massive scalar modes, again, quite like the D3-D7 system. We end with a calculation of the conductivities in the two phases.
