本文构造了三维ABJM Chern-Simons物质理论的全息对偶。味自由度是通过沿规范理论方向沿着扩展并在内部空间离域的D 6-膜来引入的。为了找到解，我们必须用D 6-膜引入的源项来求解超引力运动方程。我们得到的背景是一个运行的解决方案，表示在两个固定点之间的重整化群流，在IR和UV，在这两个几何是AdS 4 ×$ {{\mathcal{M}}_6} $的形式，其中$ {{\mathcal{M}}_6} $是一个六维紧致流形。沿着流，$ \mathcal{N} $ = 1超对称性被保留，并且味群是阿贝尔的。流是通过改变夸克质量mq产生的。当mq → ∞时，我们恢复了原始的无味ABJM解，而当mq → 0时，我们的解变得渐近等价于最近发现的无质量涂抹味的解。我们研究了动态夸克随质量变化对不同观测量的影响，如全息纠缠熵、夸克-反夸克势、高维体算符的两点函数以及介子的质量谱。
A bstractWe construct a holographic dual to the three-dimensional ABJM Chern-Simons matter theory with unquenched massive flavors. The flavor degrees of freedom are introduced by means of D6-branes extended along the gauge theory directions and delocalized in the internal space. To find the solution we have to solve the supergravity equations of motion with the source terms introduced by the D6-branes. The background we get is a running solution representing the renormalization group flow between two fixed points, at the IR and the UV, in both of which the geometry is of the form AdS4×$ {{\mathcal{M}}_6} $, where $ {{\mathcal{M}}_6} $ is a six-dimensional compact manifold. Along the flow, $ \mathcal{N} $ = 1 supersymmetry is preserved and the flavor group is Abelian. The flow is generated by changing the quark mass mq. When mq → ∞ we recover the original unflavored ABJM solution, while for mq → 0 our solution becomes asymptotically equivalent to the one found recently for massless smeared flavors. We study the effects of the dynamical quarks as their mass is varied on different observables, such as the holographic entanglement entropy, the quark-antiquark potential, the two-point functions of high dimension bulk operators, and the mass spectrum of mesons.
