Mohsen Alishahiha, Amin Faraji Astaneh, M. Reza Mohammadi Mozaffar

摘要:

给出了Einstein-Maxwell-Einstein模型中具有超标度破坏因子的Vaidya荷电黑洞的解析解,其中标量势对解的存在性起着关键作用.利用这一结果,我们研究了零电荷情况下引力描述为整体猝灭后热化过程的理论。特别地,我们用纠缠熵对系统进行了探测,发现系统在此过程中表现出一定的标度行为。

英文摘要:

We present an analytic solution of a Vaidya-charged black hole with a hyperscaling violating factor in an Einstein-Maxwell-dilaton model, where the scalar potential plays a key role in the existence of the solution. By making use of this result, we study the process of thermalization after a global quench in a theory which its gravitational description is provided by the resultant solution in the case of zero charge. In particular, we probe the system by entanglement entropy and show that it exhibits certain scaling behaviors during the process.
