荷电BTZ黑洞的纠缠熵

Entanglement Entropy for the Charged BTZ Black Hole

Alexis Larranaga

摘要:

利用AdS/CFT对应计算了荷电BTZ黑洞的纠缠熵的显式表达式。这个黑洞的熵函数的大温度展开中的主导项再现了它的贝肯斯坦-霍金熵,而代表由于量子纠缠而引起的第一次修正的次主导项表现为BH熵的对数。

英文摘要:

Using the AdS/CFT correspondence we calculate the explicit form of the entanglement entropy for the charged BTZ black hole. The leading term in the large temperature expansion of the entropy function for this black hole reproduces its Bekenstein-Hawking entropy and the subleading term, representing the first corrections due to quantum entanglement, behaves as a logarithm of the BH entropy.
