摘要:
在IIA/IIB型超弦理论框架下,我们推导了部分紧致时空$\n\mathbf{T}^n \otimes \mathbb R^{1,9-n}$中,存在$U(1)$规范势与Kalb-Ramond场时,具有横向运动的BPS D$p$-膜的左右纠缠熵(LREE)。首先我们利用复制技巧计算Rényi熵,进而得到纠缠熵。我们针对D6-膜这一特例检验了结果。此外,我们研究了与LREE相关的热力学熵,结果表明LREE与其热力学对应量精确等价。
英文摘要:
In the context of the type IIA/IIB superstring theories, we derive the left-right entanglement entropy (LREE) of a BPS D$p$-brane with transverse motion in the presence of a $U(1)$ gauge potential and the Kalb-Ramond field in the partially compact spacetime $\mathbf{T}^n \otimes \mathbb R^{1,9-n}$. At first we employ the replica trick to compute the Rényi entropy and then we obtain the entanglement entropy. We examine the results for the special case, i.e. for the D6-brane. Besides, we investigate the thermodynamical entropy, associated with the LREE. This demonstrates that the LREE is precisely equivalent to its thermodynamic counterpart.
