摘要:

我们利用全息对偶研究一维界面与两个半无限二维共形场论接触的系统。我们研究的核心是在体界面膜上引入一个动力学标量场,该标量场破坏了对偶界面场论的标度对称性,并随之对系统产生反作用。我们从全息纠缠熵定义界面熵。在零温下,我们构造了几个说明性例子,并观察到$g$-定理始终得到满足。这些例子还揭示了界面熵的独特特征,这些特征与标量势的剖面密切相关。在有限温度下,我们发现动力学标量场使体理论能够具有新的构型,而这些构型仅靠界面膜上的张力项是无法实现的。

英文摘要:

We exploit holographic duality to study the system of a one-dimensional interface contacting two semi-infinite two-dimensional CFTs. Central to our investigation is the introduction of a dynamical scalar field located on the bulk interface brane which breaks the scaling symmetry of the dual interface field theory, along with its consequential backreaction on the system. We define an interface entropy from holographic entanglement entropy. At zero temperature we construct several illustrative examples and observe that the $g$-theorem is always satisfied. These examples also reveal distinct features of the interface entropy that are intricately linked to the scalar potential profiles. At finite temperature we find that the dynamical scalar field enables the bulk theory to have new configurations which would be infeasible solely with a tension term on the interface brane.
