动态不稳定D $p$ -膜的LREE

LREE of a Dynamical Unstable D$p$-brane

Shirin Teymourtashlou, Davoud Kamani

摘要:

我们导出了玻色子D $p$ -膜的左右纠缠熵。这个膜具有切向动力学,并且被$U(1)$规范势、Kalb-Ramond场和快子场修饰。为此目的,将计算雷尼熵,然后通过取它的特殊极限,将获得LREE。此外,还对快子凝聚过程中轻稀土元素的行为进行了评价。此外,在系统发生跃迁,即不稳定膜的坍缩之后,将检验LREE的热力学第二定律。我们发现,保持第二定律施加了一些条件的参数设置。

英文摘要:

We derive the left-right entanglement entropy (LREE) for a bosonic D$p$-brane. This brane has tangential dynamics and has been dressed by a $U(1)$ gauge potential, the Kalb-Ramond field and a tachyon field. For this purpose, the Rényi entropy will be computed and then, by taking a special limit of it, the LREE will be obtained. Besides, the behavior of the LREE under the tachyon condensation process will be evaluated. In addition, after the transition of the system, i.e. the collapse of the unstable brane, the second law of the thermodynamics on the LREE will be checked. We find that preserving the second law imposes some conditions on the parameters of the setup.
