基本物质的标度不变性和anomaly:一种全息描述

Scale invariance with fundamental matters and anomaly: A holographic description

Avik Banerjee, Arnab Kundu, Augniva Ray

摘要:

一般来说,量子场论可以被认为是偏离共形场论的变形。在这篇文章中,我们假设一个简单的自下而上的模型具有全息描述,我们研究了一个假定的大N量子场论具有大的和任意数量的伴随自由度和基本自由度和非零的手征异常,在外部磁场和非零的密度的存在下。在类似条件下的量子色动力学的丰富性的启发下,我们探索的解决方案空间,以找到一个无限类的标度不变,但不是共形,场论,可能会发挥关键作用,在定义相应的物理。特别地,我们发现了两类几何:具有SL(2,R)× U(1)等距的Schrodinger等距和翘曲AdS_3几何。我们发现的迹象自发打破平移对称性,在低温下,周围的扭曲的背景。

英文摘要:

Generally, quantum field theories can be thought as deformations away from conformal field theories. In this article, with a simple bottom up model assumed to possess a holographic description, we study a putative large N quantum field theory with large and arbitrary number of adjoint and fundamental degrees of freedom and a non-vanishing chiral anomaly, in the presence of an external magnetic field and with a non-vanishing density. Motivated by the richness of quantum chromodynamics under similar condition, we explore the solution space to find an infinite class of scale-invariant, but not conformal, field theories that may play a pivotal role in defining the corresponding physics. In particular, we find two classes of geometries: Schrodinger isometric and warped AdS_3 geometries with an SL(2,R) X U(1) isometry. We find hints of spontaneous breaking of translational symmetry, at low temperatures, around the warped backgrounds.
