AdS中的纠缠熵和对偶性(4)

Entanglement Entropy and Duality in AdS(4)

Ioannis Bakas, Georgios Pastras

摘要:

利用球坐标系中一般边界条件下的引力微扰,全息计算了AdS(4)边界上圆形纠缠曲线的纠缠熵δS和模哈密顿量的期望值δE的微小变化.与热力学热力学第一定律δS = δE的一致性要求纠缠曲线的线元保持恒定。在这种情况下,我们也发现了电磁对偶性的表现纠缠熵和相应的模块化哈密顿量,以下的全息能量动量/棉花张量的对偶性。

英文摘要:

Small variations of the entanglement entropy δS and the expectation value of the modular Hamiltonian δE are computed holographically for circular entangling curves in the boundary of AdS(4), using gravitational perturbations with general boundary conditions in spherical coordinates. Agreement with the first law of thermodynamics, δS = δE, requires that the line element of the entangling curve remains constant. In this context, we also find a manifestation of electric-magnetic duality for the entanglement entropy and the corresponding modular Hamiltonian, following from the holographic energy-momentum/Cotton tensor duality.
