We study multifield extensions of Reggeon Field Theory (also equivalent to Directed Percolation model) at criticality in the perturbative epsilon-expansion below the upper critical dimension Dc=4 at one loop, for the special case when all fields have the same scale (anomalous) dimensions. Analyzing all the fixed points of the renormalization group flow for N=2 flavors and some for N=3, we find scale invariant solutions which are characterized by specific emergent global symmetries of the interacting potential. We also study two infinite families as a function of N having Z_N and S_{N+1} symmetries.
Emergent Quantum Near-Criticality from Baryonic Black Branes
在非零温度和重子化学势下,我们发现了描述“锥状规范理论“的新的黑3膜解。特别令人感兴趣的是低温极限,在那里我们发现了一种新的弱弯曲的近地平线几何;它是一个扭曲的乘积AdS_2 x R^3 x T^{1,1},其扭曲因子是AdS半径的对数的幂。因此,我们的解决方案编码了一种新型的涌现量子近临界性。我们对我们的解决方案进行一些稳定性检查。对于M理论的重子黑2-膜,我们也建立了一个渐近于AdS_4 x Q^{1,1,1}的一致性证明。
Emergent quantum criticality, Fermi surfaces, and AdS2
在有限电荷密度下,与d维场论对偶的引力解有一个近视界区域,即AdS_2 x R^{d-1}。AdS_2区域的标度不变性意味着在低能量下,对偶场论表现出由(0+1)维CFT控制的涌现量子临界行为。这种解释揭示了最近发现的费米表面的全息描述,允许分析理解其低能量激发。例如,费米面附近的标度行为由出射红外CFT中的共形维数决定。特别是,当运营商是边际在IR CFT,相应的光谱函数正是“边际费米液体”的形式,假设描述的最佳掺杂的铜酸盐。

Quantum Criticality and Holographic Superconductors in M-theory
本文给出了任意7维Sasaki-Einstein空间(SE_7)上D=11的超引力到D=4的包含度规、规范场、复标量场和实标量场的理论的一致Kaluza-Klein截断.我们使用这个D=4的理论来构造各种黑洞解,这些解描述了d=3的CFTs的热力学性质,这些CFTs对偶于偏斜的AdS_4 X SE_7解。我们发现,这些CFTs有一个丰富的相图,包括全息超导,一般来说,破宇称和时间反演不变性。在零温度下,超导溶液是带电畴壁,在远红外具有普遍的出射共形对称性。
