全息费米面与纠缠熵

Holographic Fermi Surfaces and Entanglement Entropy

Noriaki Ogawa, Tadashi Takayanagi, Tomonori Ugajin

摘要:

我们认为朗道-费米液体在纯经典极限下不具有任何引力。我们利用纠缠熵的对数行为来刻画费米面的存在性。通过引入零能条件,我们证明了比热的行为总是反常的。我们还提出了一个经典的引力对偶,它具有预期的行为的纠缠熵和比热的非费米液体。

英文摘要:

We argue that Landau-Fermi liquids do not have any gravity duals in the purely classical limit. We employ the logarithmic behavior of entanglement entropy to characterize the existence of Fermi surfaces. By imposing the null energy condition, we show that the specific heat always behaves anomalously. We also present a classical gravity dual which has the expected behavior of the entanglement entropy and specific heat for non-Fermi liquids.
